Since childhood, Warren Buffett has had a precocious investment mind and acumen for business. As a young man in Omaha, he became interested in the stock market and made his first investment (in Cities Service preferred shares) at age 11. He earned money selling peanuts and popcorn at college football games, as a newsboy delivering The Washington Post, and as the producer of a racetrack tip sheet. At age 17, he scraped together his savings to purchase pinball machines that he placed in barbershops, an investment that generated ongoing cash flow back to Buffett.
