Warren Buffett's son was at Stanford when he got $90,000 of Berkshire stock. He left school and sold it to chase music. At today's price those shares would be worth about $460 million. Peter Buffett grew up in Omaha, went to public school, and says he didn't really know how rich his father was until his 20s, when Warren showed up "on some list somewhere." At Stanford he took every intro class he could find, looking for something that clicked. Nothing did. He even asked his father about going into investing. It didn't click either, and Warren never pushed. Then a letter arrived. The first line, as Peter remembers it: "Bonanza time has arrived." His grandfather had left the grandkids a farm. Warren sold it and turned it into Berkshire stock. Peter's share was 607 or 608 shares, worth $90,000. He moved to San Francisco and sold the stock slowly to pay rent and buy equipment. There was no safety net behind it: "I never expected a dime from my parents. So I knew if I went through that $90,000, I wasn't going to get another 90." He became a composer. Years later his father gave him a billion-dollar foundation to give away, not to keep: "he gave us a billion dollars, but it's not ours." His line on risk: "you don't want to be safe and sorry." Would you have sold the shares to chase what you love, or held them and stayed at Stanford? Peter tells the whole story himself in the video below.
