How Buffett took charge: In 1965, Buffett was a shareholder in Berkshire, then a struggling New England textile company. He agreed to sell back his shares for $11.50 each, but management sent him a term sheet that showed $11.375. Angered, Buffett responded by buying all the shares he could. He won control of Berkshire on May 10, 1965. The textile business closed in 1985.

Famous Buffett quotation: "Lose money for the firm, and I will be understanding. Lose a shred of reputation for the firm, and I will be ruthless." - Sept. 4, 1991 congressional testimony about Salomon Inc, where Buffett became interim chairman to restore order after a Treasury auction bidding scandal.

Diet: Buffett likes steaks and eats candies from See's, which Berkshire owns. He estimates that one-fourth of his caloric intake comes from Coca-Cola, a longtime Berkshire investment.

Buffett on his investing record: "In 58 years of Berkshire management, most of my capital-allocation decisions have been no better than so-so. In some cases, also, bad moves by me have been rescued by very large doses of luck. ... Our satisfactory results have been the product of about a dozen truly good decisions - that would be about one every five years - and a sometimes-forgotten advantage that favors long-term investors such as Berkshire. ... The weeds wither away in significance as the flowers bloom." (Shareholder letter, Feb. 25, 2023)
