He started investing at 11. He was rejected by Harvard. He turned down a dream job to move back to Omaha and be his own boss. He refused to buy dot-com stocks when everyone said he was finished. He became the greatest investor in history by refusing to think like everyone else. At every turning point, you make the call.
This is a life simulation. At each critical moment in Warren Buffett's real story, you face the same choice he did — before you're told what he actually did.
Warren Edward Buffett was born on August 30, 1930, in Omaha, Nebraska. His father, Howard, was a stockbroker and later a congressman. By the time Warren was 6, he was buying six-packs of Coca-Cola for 25 cents and selling individual bottles for 5 cents each — a 20% markup. By 11, he had bought his first stock. By 13, he was filing a tax return that included a $35 deduction for the bicycle he used for his paper route.
The math was always obvious to him in a way it wasn't to most people. He didn't find it interesting that money grew when invested — he found it strange that most people didn't seem to find that interesting, and stranger still that they didn't do anything about it.
The question, across 80 years of investing, has always been the same: when the crowd is doing something, is Buffett right to do the opposite — or is Buffett wrong and the crowd correct?
He has been right more often than anyone in recorded financial history.
Decision 1 · 1942 · Age 11 · First Stock1 / 7
Buffett has saved $120. He buys 3 shares of Cities Service preferred stock at $38 each. The stock drops to $27. He's lost 30% of his savings. His sister Doris — who also bought shares on his recommendation — is upset. He can sell and cut the loss, or hold. What does he do?
What Warren Buffett Did
He held. The stock recovered to $40. He sold. Then Cities Service went to $202. He sold too early — and the lesson burned into him was not "hold longer" but "the business, not the price, is what matters."
Buffett has told this story hundreds of times because it contains the seed of everything. Lesson one: don't panic-sell when the price drops if the business is sound. Lesson two (the one he learned by selling at $40 when it went to $202): don't sell a great business just because you've recovered your cost. He was 11. He learned both lessons at the same time. Every major investment decision he made for the next 80 years is, in some form, an application of those two lessons.
1950 · Age 20 · Harvard Rejection
Buffett applied to Harvard Business School in 1950. He was rejected in a brief interview — the interviewer reportedly said he looked too young. This was both a humiliation and a pivot.
He had read Benjamin Graham's book, The Intelligent Investor, the previous year. He considered it the best book ever written on investing. He discovered that Graham taught at Columbia Business School. He applied. He was the only student Graham ever gave an A+ to.
After Columbia, Graham offered him a job at his investment partnership in New York. Buffett desperately wanted it. Graham initially declined — saying he reserved Wall Street jobs for Jewish analysts who couldn't get hired elsewhere due to discrimination — then relented and offered Buffett a position.
Buffett worked for Graham for two years. Then Graham retired and closed the partnership. Buffett was 26, with nowhere to go.
Decision 2 · 1950 · Age 20 · After Harvard Rejects Him2 / 7
Harvard Business School has rejected Buffett. What does he do?
What Warren Buffett Did
He applied to Columbia to study under Graham. He was accepted. He earned the only A+ Graham ever awarded. Graham offered him a job. Buffett later said: "I'm 15% Fisher and 85% Benjamin Graham." Harvard's rejection pointed him at his actual teacher.
Buffett has occasionally said that his rejection from Harvard was one of the best things that ever happened to him — not ironically, but as straightforward analysis. Harvard would have given him a credential and a network. Columbia gave him Graham. The intellectual framework he got from Graham — margin of safety, Mr. Market, intrinsic value, the difference between price and value — is the foundation of every investment decision he has made since 1950. No Harvard professor was going to give him that. The right rejection leads to the right room.
1956 · Age 26 · Omaha
Graham had closed his partnership. Buffett was 26. He had worked for the best investor in America. He could have stayed in New York, joined another firm, built a career in the world's financial capital.
He moved back to Omaha.
His friends and family thought this was strange. Omaha was not where investment managers built reputations. Buffett's explanation was simple: he could think more clearly in Omaha. New York produced noise. Omaha produced nothing but time to read and think.
He founded the Buffett Partnership with $105,100 — his $100 plus investments from family members. He charged no management fee. He took 25% of profits above a 6% annual return. He ran it from his house.
Decision 3 · 1956 · Age 26 · Omaha or New York?3 / 7
Buffett has worked for Graham and the partnership has closed. He can stay in New York — join a firm, build a network, be near the market. Or he can move back to Omaha and start his own fund. What does he do?
What Warren Buffett Did
He moved back to Omaha. He ran the Buffett Partnership from his house. Over 13 years, the partnership returned 29.5% annually — compared to the Dow's 7.4%. He never had a losing year. He dissolved the partnership in 1969 because he couldn't find undervalued stocks and took control of Berkshire Hathaway instead.
The Omaha decision is one of the most studied in investment history because it contradicts everything conventional career advice says about proximity to power. Buffett's argument was that the crowd in New York creates the crowd mentality — that being physically away from the center of market activity made it easier to see what the market was actually doing rather than what everyone said it was doing. This advantage — of deliberate distance from consensus — has arguably been the most durable structural advantage Berkshire Hathaway has had for 70 years.
1969 · Age 39 · Closing the Partnership
By 1969, the U.S. stock market had been climbing for years. Stocks that Buffett could find at obvious discounts to their intrinsic value were becoming impossible to find. The market was no longer cheap.
Buffett faced a choice that no investment manager of his stature had ever made voluntarily: close the partnership, return all money to investors, and wait — potentially years — for undervaluation to return.
He had partners who were counting on the partnership. He had fees he was earning. He had a reputation built on consistent outperformance. The pressure to stay invested — even at elevated valuations — was enormous.
Decision 4 · 1969 · Age 39 · Closing the Partnership4 / 7
Buffett cannot find undervalued stocks. The market is expensive. He can stay invested anyway — take lower returns rather than no returns — or close the partnership and return cash to investors. What does he do?
What Warren Buffett Did
He closed the Buffett Partnership in 1969 and returned all capital to investors. He told them he couldn't find undervalued stocks. The market peaked the following year. The 1970s bear market was one of the worst in American history. Partners who stayed invested elsewhere were devastated.
Buffett's letter to partners closing the fund is studied in business schools as a model of intellectual honesty. He didn't say the market was about to crash — he said he couldn't find value, and that his job was not to invest when he couldn't find value. The restraint required to close a profitable, growing fund at the height of your reputation and return money to investors is something almost no investment manager has done before or since. He then used his personal share to take control of a struggling textile company named Berkshire Hathaway — a decision he later called his biggest mistake (the textile business), because he should have bought a better business at a fair price rather than a cheap price for a bad business. Even Buffett makes mistakes. He usually documents them carefully.
1972 · Age 42 · See's Candies
See's Candies was a California candy company with a strong brand, loyal customers, and a peculiar economic property: it could raise prices every year without losing customers. Its profits were not spectacular, but they were reliable and growing.
The asking price was $25 million. By the standards of Benjamin Graham's value investing — buy at a significant discount to tangible assets — See's was expensive. Its tangible book value was $8 million. Buffett would be paying three times book value for the brand and the pricing power.
Graham would not have bought it. Charlie Munger, Buffett's new partner, thought they should. Buffett had never paid this kind of premium for anything.
Decision 5 · 1972 · Age 42 · See's Candies5 / 7
See's Candies is available for $25 million — three times its tangible book value. Graham's framework says it's too expensive. Munger says the brand and pricing power make it worth it. What does Buffett do?
What Warren Buffett Did
He bought See's Candies for $25 million. Over the next 50 years, See's generated over $2 billion in pre-tax earnings for Berkshire Hathaway on a $25 million investment — with almost no additional capital required. Buffett calls it the investment that changed his philosophy.
See's Candies was the turning point. Before See's, Buffett was a Graham disciple: buy cheap assets, wait for price to reflect value, sell. After See's — and crucially after Munger's influence — he understood that a truly great business with durable competitive advantages is worth paying a fair price for, because it will compound value for decades without needing additional capital. "It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price." That sentence — written after See's — defines Berkshire's entire investment philosophy from 1972 onward.
1987 · Age 57 · Black Monday
On October 19, 1987 — Black Monday — the Dow Jones Industrial Average fell 22.6% in a single day. It remains the largest single-day percentage decline in stock market history. Investors who had been heavily in equities lost a fifth of their wealth in hours.
The panic was total. Television showed traders on the floor of the New York Stock Exchange looking as though they were watching a disaster in slow motion. Volume was at record levels. The phone lines to brokerages were jammed with sell orders.
Buffett did nothing. Then, the next day, he bought more Coca-Cola.
Decision 6 · 1987 · Age 57 · Black Monday6 / 7
The Dow has dropped 22% in a single day. Every indicator says a crash is underway. Buffett holds significant positions in equities. What does he do?
What Warren Buffett Did
He didn't sell anything on Black Monday. He started buying Coca-Cola stock in the following months — buying quietly through the market turmoil until Berkshire owned 7% of the company by 1989. The Coca-Cola position is now worth over $25 billion on a $1.3 billion investment.
Buffett's explanation for not selling during Black Monday is characteristic: "The stock market is there to serve you, not to instruct you." A 22% drop in one day doesn't mean the underlying businesses are worth 22% less — it means a lot of people are panicking simultaneously. Panic creates opportunity. His purchase of Coca-Cola after the crash — a consumer products brand with consistent pricing power, global distribution, and a century of brand equity — was a direct application of everything he had learned from See's Candies. The business decides the value. The market decides the price. The gap between the two is where the money is.
1999 · Age 69 · The Dot-Com Bubble
In 1999, the internet bubble was at its peak. Technology stocks were rising 100%, 200%, 300% in months. Amazon, Pets.com, Webvan, Cisco, Intel — every tech stock seemed to defy gravity. Analysts on television were naming price targets that assumed infinite growth forever.
Berkshire Hathaway's stock price declined by 19.9% in 1999. The S&P 500 was up 21%. Warren Buffett was being openly mocked. Barron's published a cover story titled "What's Wrong, Warren?" Forbes published a column arguing that Buffett had "lost his touch" and didn't understand the new economy.
He didn't buy a single internet stock.
Decision 7 · 1999 · Age 69 · The Dot-Com Bubble7 / 7
Berkshire is down 20% while tech stocks are up triple digits. The financial press says Buffett has lost his touch. He doesn't understand the new economy. He has the capital to participate. What does he do?
What Warren Buffett Did
He bought nothing. He gave a speech at Allen & Company's Sun Valley conference in July 1999 explicitly predicting that internet stock returns would disappoint. He was publicly mocked. In March 2000, the Nasdaq began its 78% decline. Berkshire rose 49% from 2000 to 2002 while the market collapsed.
The 1999-2000 dot-com episode is considered the clearest demonstration of Buffett's most fundamental quality: the ability to hold his position when the entire world is telling him he's wrong. This is not stubbornness — it's the specific form of intellectual confidence that his entire career is built on. He has a framework. He applies it consistently. When the framework says don't buy, he doesn't buy. When the crowd says the framework is broken, he says: "Then let's see." He is still in Omaha. Berkshire Hathaway is still the company he controls. He is still buying businesses with durable competitive advantages at prices below their intrinsic value. He has been doing this for 70 years. He has not had a decade where his framework failed to work.
Omaha, Still
Warren Buffett still lives in the house he bought in 1958 in Omaha, Nebraska, for $31,500. He still eats at the same diner. He still drinks multiple Coca-Colas a day. He is, at this writing, the sixth-richest person in the world, with a net worth of approximately $130 billion, the large majority of which he has pledged to charity through the Giving Pledge.
He has given away more money than any individual in American history — over $50 billion, primarily to the Bill & Melinda Gates Foundation and to his children's foundations.
He started investing at 11. He is still doing it at 94.
His most important quality is not his intelligence — there are smarter people who have made less money. It's not his work ethic — he reads for five to six hours a day, but many people work harder. It's not his network — he deliberately built one in Omaha rather than Wall Street.
It is his willingness to be wrong in public, for years, while being right in principle. The crowd is usually wrong at the extremes. Being right at the extremes requires being willing to be alone there. Most people find that intolerable. Buffett has found it comfortable for 80 years.
