Founders, allocators, paintings, obsessions. The writing stays at the front door. This is everything behind it.
tap the ring, or just click hereEvery room tells on its owner. This one holds the founders I treat as case files, the investors I read like philosophers, six hundred years of people funding the future, and the paintings that taught me more about conviction than any pitch deck. Take your time. Touch things. Some of them touch back.
You found the room behind the writing. Come in. The coffee is imaginary but the chairs are real, and you’re welcome to touch everything.
I’m Pedrum. I’ve built companies, just finished an MBA, and I’ve noticed that everything I actually believe came from three places: studying people who built things, studying people who funded things, and standing in front of paintings I didn’t understand until suddenly I did. This room holds all three, plus the reading that feeds them.
Most personal websites are résumés wearing cologne. This one is closer to a studio a friend lets you wander through while they make coffee. The case files stay open on the desk, the ledger is honest, the blackboard still has chalk on it. Nothing here is comprehensive. Everything here is chosen, and everything earns its place by changing how I operate, not by being famous.
Three ways to use it: read it like an essay, raid it like a library, or scroll straight to the blackboard and draw on my wall. All three are correct. A fourth way exists for the curious; the colophon has hints.
Start with the sixteen-year-old bookkeeper who fell in love with a ledger. Or the seamstress who turned underwear fabric into an empire, or the engineer who was told his life’s work was scrap. Every file in this drawer begins the same way: a person standing at a fork where the sane road was clearly marked, choosing the other one. Open a file; each ends with what I actually took from it. Open all twenty-five and the drawer gives up its secret.
A thirteen-year-old telegraph messenger who learned to read the wire by sound, then rode the railroads, then bet everything on the Bessemer process while rivals called steel a fad. His mills ran on obsessive cost sheets; he cared less what a ton sold for than what it cost, because cost was the number he controlled. In 1901 he sold to Morgan for $480 million and then executed the stranger half of his plan: giving nearly all of it away on a system, funding more than 2,500 libraries so the next messenger boy could read his way up too.
What I take The exit is the midpoint. What you do with the second half is the actual biography.
Before he owned the oil business he owned its arithmetic. As a sixteen-year-old assistant bookkeeper he treated the ledger like scripture, and he never stopped: while rivals guessed at their refining costs, Rockefeller knew his to the third decimal, per barrel, per barrel-hoop, per drop of solder on a can lid. The empire followed the precision, not the other way around. His real product was never oil. It was certainty about costs in an industry running on rumor, and that certainty let him price rivals into selling and railroads into secret rebates.
What I take Knowing your numbers colder than anyone else is a weapon, not a chore.
She couldn’t afford advertising, so she gave the product away: a lipstick into every stranger’s hand, a free touch-up at every counter, a sample in every bag whether you bought or not. The industry called it ruinous. It was actually a distribution system disguised as generosity. Every woman who walked out with a miniature became a saleswoman at her own dinner table, and the “gift with purchase” she pioneered is now the entire cosmetics industry’s standard weapon. It began as the strategy of someone too poor for billboards.
What I take When you can’t outspend, out-give. Generosity compounds like capital.
The moving assembly line cut the time to build a Model T from about twelve hours to about ninety minutes, and the price fell year after year while wages went the other way: in 1914 Ford stunned the industry by roughly doubling pay to five dollars a day. Moralists called it charity and rivals called it madness; it was neither. Turnover collapsed, the best mechanics in America lined up at his gate, and his own workers became his customers. He understood that a mass market has to be paid into existence.
What I take Speed comes from removing motion, not adding effort. And your ecosystem is something you fund, not something you find.
An orphanage seamstress who rebuilt women’s clothing out of jersey, a humble knit then used mostly for men’s underwear, because it was cheap, and because women could finally move in it. She borrowed from menswear, cut away ornament, and made simplicity the most expensive look in the world. The cautionary chapter matters too: in 1924 she signed away ninety percent of her perfume business to partners in a deal she spent decades fighting, and only renegotiated her way to a fortune in 1947. She invented modern luxury and nearly gave away its best asset at the same desk.
What I take Subtraction can be a revolution. Also: read the deal twice, especially when the product is your own name.
Hollywood called Snow White “Disney’s Folly”: a feature-length cartoon, three years late, wildly over budget, financed by a bet-the-studio bank loan. It became the highest-grossing film of its era. Twenty years later the banks laughed at an amusement park, so he borrowed against his own life insurance to start Disneyland, then rewrote the company’s entire vocabulary around it: employees became cast members, customers became guests, shifts became the show. He understood that language is architecture. Rename the work and you change how it’s done.
What I take Build the world, not just the product. And name things like the names matter, because they do.
He flew a secondhand plane low over county roads to count cars in competitors’ parking lots, walked every rival’s aisles with a notebook, and stood in his own doorways asking customers what he’d gotten wrong. The genius wasn’t the discounting; everyone discounted. It was the refusal to let any layer of management stand between him and ground truth. Data flowed up to Bentonville every Saturday morning while his competitors waited for quarterly reports, so Walmart simply turned its inventory faster than anyone could copy.
What I take Consensus is a lagging indicator. Parking lots are a leading one.
In 1955 Bulova offered to buy a hundred thousand of Sony’s transistor radios, an order bigger than the company itself, on one condition: Bulova’s name on the case. Morita, whose country’s exports were still a punchline for shoddiness, said no. He reasoned that he was being asked to sell the only asset that compounds forever: the name. Fifty years of Trinitrons and Walkmans later, “Made in Japan” meant precision, and that single refusal is as responsible as any product.
What I take Never sell the compounding asset to finance the depreciating one.
A dyslexic farm boy who started by selling matches from a bicycle, then seeds, then pens, then furniture by catalog. The founding accident became doctrine in 1956 when a colleague sawed the legs off a table to fit it in a car: flat packing moved assembly, shipping, and warehousing onto the customer, and IKEA quietly pocketed the difference as permanently lower prices. Kamprad flew economy, drove an old Volvo, and wrote frugality into a founder’s testament, because he understood that cost discipline is a culture, not a spreadsheet, and cultures are the only cost programs that survive their author.
What I take Every cost you remove is pricing power you keep forever. Inconvenience, priced honestly, is a business model.
Toyota rejected his first batch of piston rings: years of work, judged scrap. He went back to school for metallurgy, remade them, and won the contract; then war and an earthquake took the factory anyway. He started over with surplus generator engines bolted to bicycles. What never changed was the order of his loves: the machine first, the market second. He tuned engines by ear the way conductors tune orchestras, and entered the Isle of Man TT, the world’s hardest race, as a company announcement rather than a marketing stunt. The market forgave every setback because the machines kept getting better.
What I take Obsession with craft survives disasters that strategy doesn’t.
Twenty-five years at Texas Instruments, passed over for the top job, and then the founding at an age when most executives are writing memoirs: recruited to Taiwan, he started TSMC in 1987 at fifty-five, on a business-model inversion nobody wanted. Make everyone’s chips; design none of your own; compete with no customer, ever. The pure-play foundry seemed like humble contract work. It is now the hinge on which the entire world economy swings, and arguably the most consequential company founded in the last half century.
What I take Being passed over can be the founding event. And a new business model beats a new product, because a model is a treaty everyone signs.
The famous version is the keynote messiah. The useful version is the man who audited a calligraphy class with no plan, got fired from his own company, and spent the wilderness years running NeXT and a struggling animation studio, only to return with the exact toolkit Apple needed: typography, operating systems, and storytelling. None of it looked like a career. All of it was the moat. Taste, it turns out, is accumulated in detours, and Apple’s margins are what taste looks like on an income statement.
What I take The detour you can’t justify today is often the edge you’ll monetize in a decade.
In 1976 he wrote an open letter scolding hobbyists for copying software, insisting that code, though free to duplicate, still deserved a price. That single stubborn idea became an industry. The masterpiece came in 1980: IBM needed an operating system, Gates bought one from a small Seattle shop for a modest sum, licensed it to IBM non-exclusively, and kept the right to sell it to every clone maker on earth. IBM got a product; Gates got the standard. It remains the most leveraged deal in business history.
What I take Own the thing that licenses, not the thing that ships. The margin lives in the rights, never in the box.
He joined Apple in 1998, when it was months from irrelevance, and did the unglamorous surgery: closed the factories, outsourced with precision, and drove inventory from months of stock to days, treating logistics with the same fanaticism the design studio reserved for corners and radii. Then he took the hardest job in business, following a founder-myth, and refused to impersonate him. He ran the company as an operator: services, silicon, privacy as policy, and roughly a tenfold rise. The quiet lesson is that operations, done obsessively, is strategy, and succeeding a genius is its own genius.
What I take Don’t play the predecessor’s instrument. Master your own and let the company compound.
For its first decade, Blue Ribbon Sports was a company perpetually one bank meeting from death. Knight kept his accounting job to make payroll, begged letters of credit, and lived on float. The lesson buried in his memoir isn’t inspiration; it’s duration. The dark middle of a company lasts years longer than any founding myth admits, and the ones who make it are rarely the most brilliant. They’re the ones who arranged their lives so they could keep going while nothing worked.
What I take Structure your life to survive the middle. The middle is most of it.
In 1984 he bought a bankrupt textile conglomerate, mills and diapers and department stores, because buried in the wreckage sat one asset the accountants had no line for: Christian Dior. He sold everything else. The insight that built LVMH is that a great name is stored desire, and desire has software economics: near-zero marginal cost, pricing power that rises with scarcity, and no expiry date if maintained. He then applied the discipline luxury lacked, real logistics and real balance sheets, without ever letting the customer see the machinery.
What I take Inside every distressed asset, look for the one thing that compounds. Buy that; sell the rest.
The 1997 shareholder letter reads like a dare: we will be misunderstood for long periods, we will price for market leadership rather than quarterly optics, and we will make bold bets where the odds are good but the outcome uncertain. Then he reprinted it every single year, an annual public contract with his own time horizon. Everything distinctive about Amazon, from AWS growing out of internal plumbing to a decade of “unprofitability” that was actually reinvestment, falls out of one variable set differently: the clock.
What I take Most competition dissolves the moment you genuinely change the time horizon.
NVIDIA nearly died in 1996; Huang laid off most of the company and bet the remains on a single chip. That’s the ordinary part. The extraordinary part came later: spending roughly a decade building CUDA, an entire programming platform for computation nobody was asking for, while Wall Street treated it as the expensive eccentricity of a video-game company. When deep learning arrived, the only shovels in the store were his. The bet was never a secret; he explained it constantly. People just found it boring to believe him.
What I take You can announce your decade-long bet out loud. Almost nobody will bother to front-run conviction.
The founding argument was arithmetic: a rocket’s raw materials cost a small fraction of its sticker price, so the price was convention, not physics. Reusability was ridiculed by an industry that had priced in throwing the machine away. The stress test came in a single December in 2008, when SpaceX was one failed launch from the end and Tesla’s rescue financing closed on Christmas Eve; both survived by days. Whatever else one thinks of the noise around him, the method is worth filing: price the physics, not the precedent, and size your commitment so survival itself is the moat.
What I take First principles are a demolition tool. Use them on the invoice everyone else accepts.
Two graduate students who treated the web like academia and links like citations: a page mattered if pages that mattered pointed at it. PageRank was a library science idea wearing a search box. The part I keep is the humiliation: in 1999 they tried to sell the whole thing to Excite for under a million dollars, and were turned down. The market’s no forced them to build the company instead, and the auction they later bolted onto search became the most profitable business model of the internet era.
What I take Sometimes the market refuses you into greatness. Keep a list of your rejections; one of them is a gift.
He built an online snowboard shop, hated every e-commerce tool available, and wrote his own. The snowboards were the false start; the realization that the tooling was the company was the founding. Shopify’s strategy has stayed weirdly consistent ever since: arm the rebels. Give a million small merchants the infrastructure of a giant and take a sliver of everything that flows through. It’s the rare platform-era company whose incentives point the same direction as its customers’.
What I take The tool you built out of frustration for yourself is the most honest market research that exists.
Every Western platform assumed the social graph was the product: you see what your friends share. Zhang bet that the graph was actually the bottleneck, and that a recommendation engine reading behavior directly could out-program your friends within a week of watching you. TikTok is that bet at planetary scale, and it quietly rewrote the job description of every feed on earth. I think about him the way one thinks about weather: not admiringly, but attentively. My essay on machines occupying time is, in part, about what he proved.
What I take Interface decisions are destiny. Whoever chooses what you see next is the real editor-in-chief.
When nobody would fund air mattresses for strangers, he sold novelty election-themed cereal to stay alive, which sounds like a joke until you see what it signals: a founder who will manufacture survival out of anything. The deeper contribution came after. Airbnb’s real product was never lodging; it was engineered trust. Reviews, identity, photography, guarantees: an apparatus that made sleeping in a stranger’s home feel safer than a hotel chain. He treated trust as a design problem with components, not a vibe.
What I take Trust can be decomposed, designed, and shipped like any other feature. Most markets are missing exactly that.
Online payments circa 2010 meant weeks of paperwork with a bank’s gateway partner. Stripe’s founding artifact was seven lines of code a developer could paste before lunch. The Collisons picked the least glamorous layer of the internet, money plumbing, and treated it with the care other companies reserve for logo redesigns: obsessive documentation, APIs as literature, infrastructure as a form of ambition. Then they kept widening the aperture until the company behaved like infrastructure for the GDP of the internet.
What I take Pick the boring layer everyone depends on and make it beautiful. Boring plus beautiful is a monopoly.
Five thousand one hundred and twenty-six failed prototypes of a bagless vacuum, built over fifteen years in a coach house while the appliance giants declined to license the thing that would obsolete their bag business. So he manufactured it himself, kept full ownership, and let the failures become the company’s culture: engineers there are hired to be wrong quickly. The prototype count is the point. Most people quit somewhere in the first hundred; the moat begins around prototype three thousand, where nobody is willing to follow you.
What I take Iteration is a moat precisely because it’s miserable. Count your prototypes and keep going.
You opened all twenty-five files. That’s not browsing; that’s studying, and studying is how every file above got started. This one is blank on purpose. The founders in this drawer had ledgers, prototypes, refusals, and dark middles. What they did not have was any certainty that their file would end up in someone’s study. Neither do you. That’s the deal.
What I take Nothing yet. The file is open. Write something worth filing.
Every investor on earth is answering the same terrifying question: what do you believe enough to pay for? These ten answered it best. One nearly lost everything in 1929 and turned the scar into a method. One banned storytelling from the building entirely. One left Wall Street for a university job and quietly beat almost everyone. No accordions here; the whole ledger stays open.
He was brilliant before 1929 and nearly wiped out anyway; the crash took most of his partnership’s capital while he watched. Everything he codified afterward is scar tissue turned into method: buy so far below conservative value that being wrong is survivable, treat the market as a manic counterparty rather than an oracle, and never confuse a good company with a good price.
Margin of safety is humility expressed in arithmetic.
The public knows the compounding; the professionals study the sitting. Buffett’s edge was never information. It was the temperament to hold cash for years while being called a has-been (1969, 1999), then act in size within days when the odds finally tilted. He tells students to imagine a punch card with twenty lifetime slots. The scarcity is the discipline: almost everything, including almost everything good, must be let go past.
Inactivity is a position, and most of the time it’s the correct one.
A lawyer who read physics, biology, and psychology and refused to accept that finance had its own sealed logic. His latticework method, hanging every decision on the big models of many disciplines and letting them argue, is really a defense system against the brain’s shortcuts, which he catalogued more honestly than most psychologists. His favorite operation was inversion: don’t ask how to succeed. Ask what guarantees ruin, then avoid it.
Invert, always invert. The exits are marked more clearly than the entrances.
His memos built a career out of one honest admission: you cannot know the future, but you can know where you stand. Marks reads markets like weather systems, never predicting the storm’s hour but noticing when everyone has stopped carrying umbrellas. First-level thinking says a great company is a great stock; second-level thinking asks what’s already in the price. The pendulum between greed and fear never stops. His entire method is knowing which direction it’s currently swinging from.
You can’t predict. You can prepare.
Thirteen years running Magellan at roughly 29% a year, and the detail that haunts me isn’t the return. It’s the finding, often repeated, that many of his own investors still lost money, because they piled in after hot streaks and fled after dips. The fund compounded; the behavior didn’t. His method was almost insultingly humble: know what you own, be able to explain it to a teenager in two minutes, and notice what’s in your own cart before Wall Street does.
The instrument doesn’t make the return. The holder’s behavior does.
He wanted to be a philosopher and, in a sense, succeeded: reflexivity, the idea that markets don’t merely read reality but write it as rising prices change the fundamentals that justify prices, is a genuine contribution to epistemology that happened to pay. Sterling, 1992: when conviction and setup aligned, he didn’t nibble. He bet ten billion against the Bank of England and broke the peg. The philosophy chose the trade; the sizing made it history.
Markets are participants in the reality they price.
Thirty years of roughly 30% annually and, by his account, no down year. Built not on being right more often, but on a violent asymmetry of expression: tiny when uncertain, enormous when the setup screams, and out instantly when the thesis cracks. He credits Soros with the lesson that separates professionals from talented amateurs: it’s not whether you’re right or wrong. It’s how much you make when right versus how much you lose when wrong.
Conviction without sizing is just opinion.
A world-class geometer who walked away from mathematics, hired physicists and codebreakers instead of MBAs, and banned narrative from the building: if the signal is real, trade it. Nobody needs to explain why. The Medallion fund’s returns, decades of them, are the most uncomfortable dataset in finance, because they suggest the stories everyone else trades on are mostly decoration. I keep him around as a standing rebuke: maybe the narrative is the bug.
The market owes your story nothing.
He left Wall Street for a university job that paid a fraction of what he was worth, then quietly rewrote institutional investing: out of bonds, into venture, private equity, timber, and absolute return, harvesting the premium the impatient leave on the table because a university thinks in centuries. The Yale Model made billions for education, and his students went on to run half the endowments in America. The part I underline isn’t the allocation. It’s the career: he priced meaning into the compensation.
Time horizon is an asset class. So is working on something you love.
A Harvard professor who institutionalized a new asset class: in 1957 his American Research & Development put about $70,000 into two engineers called Digital Equipment and watched it become $355 million, the proof-of-concept for all venture capital since. But his actual doctrine was stranger and better than returns. He said he was building men and companies, in that order, and held positions for decades like a gardener, not a trader.
Back the person; the company is the byproduct.
Some numbers are stories with the boring parts removed. A count of failed prototypes. The price a man accepted for ten percent of Apple. One year, 1891, that quietly explains half my essays. These live in my head rent-free; below, what each of them pays for the room.
History’s most expensive word has two spellings. Decca spelled it at four boys from Liverpool and Kodak spelled it at its own invention; Morita spelled it at Bulova and built Sony out of the syllable. Same word, opposite fortunes. The difference, every single time, is what the refuser understood about time.
Pull one thread: who wrote the check? Behind Brunelleschi’s dome stands a banker. Behind the computer age, a professor with a strange new fund. Keep pulling and six hundred years unravel into a single relay, hand to hand since Florence, each runner passing the next a tool that didn’t exist before. The baton is currently in the air.
Banking made the money; patronage made the point. Cosimo funded Brunelleschi’s impossible dome and Donatello’s bronzes the way a modern fund seeds moonshots: diversified bets on unproven genius, held through ridicule, with returns denominated in a changed city. The Renaissance had a cap table.
The first titan of finance in the modern sense: he funded emperors’ elections, priced sovereign risk when the concept barely existed, and demanded information from a courier network faster than any crown’s. He also built subsidized housing for the poor that still stands, five centuries of rent set at one symbolic guilder.
From a ghetto coin shop he placed five sons in five cities, Frankfurt, London, Paris, Vienna, and Naples, creating the first truly international capital network. The family’s couriers and pigeons moved market-moving news ahead of governments; the structure itself, a distributed partnership with shared intelligence, was the innovation.
In the panic of 1907, with no central bank in existence, one private citizen locked the heads of New York’s banks in his library until they pledged the capital to stop the run. He electrified the country as Edison’s financier, consolidated railroads and steel, and demonstrated capital’s strangest power: to be, for a moment, the state.
After the crash nearly ruined him, he did something no financier had bothered to do: he wrote the discipline down. Security analysis became teachable, testable, arguable, a craft with a textbook instead of a temperament. His Columbia classroom became the industry’s seed crystal, and his best investment was a student from Omaha.
He took Graham’s era of buying existing value and inverted it: what if the discipline was applied to things that don’t exist yet? ARD was the first institutional venture fund, DEC its proof, and his Harvard students, swarming out into the industry he invented, his real portfolio.
When eight young scientists wanted to leave Shockley’s lab in 1957, it was Rock who found the money that let them found Fairchild, the big bang of Silicon Valley. He backed Intel on a page-and-a-half memo and Apple soon after, and coined the term for the job itself: venture capitalist. Talent, he showed, is the scarce asset; capital merely follows it west.
The Sequoia founder’s heresy was “bet on markets, not founders”: a giant wave forgives a mediocre surfer. From one office on Sand Hill Road he funded Atari, Apple, and Cisco, sometimes installing the management himself. The market-first lens and the founder-first lens have been arguing productively ever since; both sides of that argument trace to him.
He democratized the entry ticket. Y Combinator replaced country-club introductions with an application form and an essay culture that treated startup formation as a teachable craft: small checks, big batches, advice in public. Thousands of companies later, the most radical part is still the first part. Anyone can apply.
Six hundred years, one job, new tools every generation: the ledger, the network, the backstop, the method, the fund, the memo, the application form. The lineage doesn’t end. It recruits.
These are the pencil marks that pile up while writing essays at one in the morning: half conclusions, half open questions wearing confident clothes. Thirty of them, grouped by obsession. Or press the button and let the room deal you one at random.
Eighteen books survived the cull, and every survivor got read twice. Each earned its shelf space by changing a real decision, not by being famous. Attached to each: the idea I walked out with, in my own words, because what survives translation into your own head is the only part of a book you ever truly own.
Not an investing book. An operating system: speeches, checklists, and the psychology of misjudgment, assembled like a cathedral of common sense.
The idea I keep: borrow the big models from every discipline and let them argue about your decision before you make it.
Two chapters carry the whole edifice: the market as a moody business partner, and the margin of safety. The rest is scaffolding you climb once.
The idea I keep: price is a quote, not a verdict. You’re allowed to hang up the phone.
Rockefeller rendered as a system rather than a villain or saint: ledgers, silence, Baptist thrift, and ruthlessness braided into one coherent machine. The best business biography ever written.
The idea I keep: mastery of detail scales into mastery of industry. There is no shortcut through the arithmetic.
Compounding as autobiography: money, yes, but also relationships, reputation, and regret, all rolling downhill and gathering mass. Painfully honest about the costs.
The idea I keep: everything in a life compounds, including the things you neglect.
The founder memoir with the anesthesia turned off: a decade of near-death, debt, and doubt, written by someone who remembers being terrified rather than retrofitting confidence.
The idea I keep: the dark middle is most of the story. Build a life that can afford to stay in it.
How a defeated country’s engineers rebuilt its name one transistor at a time, and a masterclass in refusing short money that costs you the long asset.
The idea I keep: a brand is a nation-sized story told through the smallest details of a product.
Amazon’s DNA sequenced: regret minimization, customer obsession as a forcing function, and the strange power of a company that treats its own margins as a public menu for competitors.
The idea I keep: your margin is someone’s opportunity. Ideally yours, before it’s theirs.
A contrarian catechism. Half the claims are wrong on purpose so you’ll argue with them, which is the actual pedagogy. Nobody leaves neutral.
The idea I keep: competition is a tax on sameness; secrets are the only rent-free real estate left.
Management writing that starts where the frameworks end: layoffs, demotions, fear at 3am. The struggle, named precisely, loses about a third of its power over you.
The idea I keep: there is no formula for wartime. There is only the practice of deciding anyway.
Pixar’s president explaining, with unusual honesty, that every great film they made was bad for years first, and that the machinery protecting ugly early drafts from premature judgment is the actual studio.
The idea I keep: build a braintrust that critiques the work, never the person, and let candor outrank hierarchy.
Twenty short essays proving that finance is a branch of psychology with decimal points. The rare money book your family should read before your analyst does.
The idea I keep: wealth is what you don’t see. The cars not bought, the exits not taken, the optionality quietly held.
The grave dancer’s memoir: a career built on buying what everyone else was fleeing, from distressed real estate to entire industries, told with zero interest in being liked.
The idea I keep: when everyone is looking right, look left. Supply and demand is the entire textbook; the rest is commentary.
The bug report for the human mind, filed by the person who found the bugs. Read slowly; you will catch yourself committing each chapter in real time.
The idea I keep: the confident voice in your head is a press secretary, not a scientist.
Written about television in 1985; reads like a code review of the feed. Postman saw that the medium doesn’t carry the culture. It becomes it.
The idea I keep: every medium smuggles in an epistemology. Ask what a technology makes easy to believe.
The prequel to everything I write about: two centuries of the harvest and resale of human attention, from penny press to platform. The pattern repeats so cleanly it’s almost funny.
The idea I keep: wherever attention pools, an industry forms to drain it. Guard the reservoir.
A fable short enough for an afternoon and heavy enough for a lifetime: the revolution succeeds, and then the commandments on the barn wall start getting quietly edited at night. The sharpest book ever written about how power captures the language before it captures anything else.
The idea I keep: whoever controls the definitions controls the farm. Reread it before reading any regulator’s press release.
Why things catch on, taken apart like an engine: social currency, triggers, emotion, visibility, usefulness, and story. The rare marketing book built on research rather than war stories, and it explains everything from viral videos to why some products advertise themselves.
The idea I keep: word of mouth is engineered, not lucky. Design the retelling, not just the telling.
A head of state journaling at night, for himself, with no audience intended, which is exactly why it works. Two thousand years of executives have found their own worries pre-answered.
The idea I keep: you don’t control events; you control the account you give of them. That account is your actual life.
Modern art gets accused of being something a child could make. Almost right: it’s the discipline of finding your way back to the mark a child makes, which takes most of a lifetime. Ten walls, each label carrying a mark of my own drawing in the artist’s spirit. No velvet rope, no hushed voices required.
The patron saint of this website. He left America at the height of Abstract Expressionism, moved to Rome, and spent fifty years making paintings that look like a wall a poet leaned against: scrawled names of Achilles and Apollo, loops of pencil like handwriting with the language removed, chalk lines on slate-dark grounds that his blackboard series turned into pure velocity. Critics called it graffiti; it hangs on a ceiling of the Louvre now. What he proved matters to anyone who writes or invests: a gesture can carry as much intelligence as a sentence, and restraint, knowing how little to put down, is the last skill acquired.
Two rectangles of color, and grown adults cry in front of them, which was the entire point. He insisted the paintings were about tragedy, ecstasy, doom, not color relationships, and hung them low and close so you’d fall in. Weather systems for the interior life.
Grids ruled by hand in pencil on six-foot canvases: perfection attempted, never quite reached, on purpose. From across the room they dissolve into weather. She lived alone in the New Mexico desert and called the work discipline in the service of joy. It reads like meditation you can hang.
Identical boxes in machined aluminum, spaced with fanatical precision: sculpture that makes you notice the room, the light, and your own position in it. He wrote furiously against decoration and bought a Texas town to install things permanently. Every product designer chasing inevitable-looking simplicity is downstream of Marfa.
He crossed out words so you would read them harder, his own trick, stated openly. Anatomy diagrams, crowns, lists of kings: the canvases read like a mind annotating itself at full speed. Dead at twenty-seven, and the auction market has been apologizing ever since. Energy as argument.
Started by repainting bus-shelter ads without permission; ended up in museums and on every continent’s skyline as hundred-foot balloons. The crossed-out eyes are a bet that the line between gallery and street was always a business-model question, and he arbitraged it. Sentiment and commerce, holding hands, no apology.
Nearly five decades of Date Paintings: the day’s date, hand-lettered in white on a monochrome ground, finished by midnight or destroyed. No expression, no image, just the fact of another day survived and recorded. The purest artwork ever made about time, and the standing question behind my second essay: what is your daily mark, and would you dare make it public? The date on this label, by the way, is today’s. It repaints itself for every visitor.
He mixed a blue so saturated it seems to hum, registered the recipe as International Klein Blue, and then sold entire canvases of nothing else. It worked, because the color was the brand and the brand was the argument: ownership of a feeling. He also once sold empty space for gold and threw half the gold in the Seine. The most honest luxury business ever run.
He found his shapes by looking hard at the world’s leftovers: the shadow under a bridge, the curve of a window, a shirt on a line. Then he painted just the shape, enormous, one color, no story. The lesson hiding in all that serenity: seeing is a form of editing, and the confidence to show one shape is rarer than the ability to show many.
Photorealistic paintings blurred as if memory itself smudged them; then, from the same hand, abstractions dragged into being with a squeegee the size of a door. Refusing to pick a style was the style. Range as a philosophical position: no single way of seeing gets to claim the truth.
Everything below feeds the work without looking like work: the rooms worth crossing oceans for, the films that actually understand ambition, and the records these essays were written to. Open whichever drawer matches your evening.
Places that rearranged me, or are queued to. Art mostly, capital once; the itinerary of this whole website.
Films that understand building, wanting, and the bill for both. Wall labels only; bring your own popcorn.
Music for long paragraphs: mostly instrumental, mostly patient, all of it structurally honest. Each one earns its place for a reason beyond the sound.
Tap a word and it opens like a compressed essay on the slate below. This is the vocabulary I reach for when a decision refuses to simplify: twenty tools, most of them older than any framework and sharper than most. Somewhere in here is the word you’ve been missing all week.
The essays are the arguments I’ve finished; these cards are the ones still open on the desk. Every card has a back. Flip it for my current lean, then argue with me by mail. The leans change. That’s what makes them leans.
The best business education was never in a classroom. It has been published, quietly and mostly for free, a few pages a year, by the people who actually did the thing. I’ve arranged the five collections I raid most into rooms. Pick a door; steal an education.
The essay culture that half this site descends from. His archive is free and dangerously long; these are the doors I hand people first, each with the reason I keep going back. The notes are mine; the essays are his, one click away.
Sixty years of plain-English shareholder letters, free on a website that looks unchanged since 1997, which is itself a lesson. Better than most MBA programs and considerably cheaper. Start with these vintages; my sommelier notes attached.
The books are the polished lectures; the memos are the lab notebook, written to clients in real time as cycles turned. Even Buffett has said he reads them the moment they arrive, which is the only blurb that matters.
Twenty-four shareholder letters, and the first one reprinted at the back of every single one that followed: an annual public renewal of the same vows. Read them in order and you watch a bookstore become an everything store become infrastructure.
The living writers and rooms I return to on a schedule. Not endorsements; dependencies.
Thirty-three machines in eight wings live behind this door: a machine that compounds, a coin that streaks, a punch card that doesn’t forgive, and a dial you probably shouldn’t turn all the way. The lab grew loud enough to earn its own wing: markets you can panic-sell, a universe you can zoom, another you can paint into being. Bring ten minutes and some honesty.
Enter the experiments →In the late sixties Twombly painted loops of white line on slate-dark grounds: handwriting with the language removed, velocity made visible. Here is a small one of your own. White chalk, orange chalk, a date stamp, and a wipe. Nothing is saved unless you keep it. That’s the point.
P.S. stands for postscript. It also stands for Pedrum Shokouhi. This was not an accident. The whole site is a postscript to the day’s thinking, and the world is the postscript to the writing.
Set in Georgia for the reading, Helvetica for the labels. One orange, #FF4D00, used the way Twombly used red: rarely, and therefore loudly. Hand-built as plain HTML and CSS. No framework, no tracker, no cookie banner, no analytics watching you read. Served from Cloudflare’s edge, so it loads fast from anywhere on earth.
Influences, gratefully stolen: Jony Ive’s conviction that restraint is a feature; Virgil Abloh’s quotation marks and his license to put your influences in the open; KAWS’s refusal to choose between art and commerce; Cy Twombly’s chalk; and the essay culture of a certain orange startup school. The essays, not the merch.
Five of them, since you asked. One answers to old video-game wisdom, typed on a keyboard. One belongs to Twombly’s name, also typed. One waits until every case file is open. One lives in the developer console, for people who look behind walls. And the tab itself gets lonely when you leave it. On a phone? Press and hold the P.S. up top instead of the video-game one. Happy hunting.
The writing lives at the front door. If you read only one thing, make it an essay. This room is just the margin notes that surround them.
