Warren Buffett may be among the world's richest men, but you wouldn't know it if you met him. He wants to be liked far more than he wants to be famous, and his sense of humor is far more indicative of his personality than his ego.

And they don't call him the “Oracle of Omaha” for nothing. By the age of 14, Buffett had purchased a small farm in his hometown of Omaha, Nebraska, using the profits from his paper route. By the time he graduated college, he had $90,000 in savings.In 1962, Buffett became a millionaire with his Omaha-based investment partnership, Buffett Partnership, Ltd. He began buying shares of a textile manufacturing company, Berkshire Hathaway, and eventually took control of the company. By 1990, he was a billionaire.

Today, he’s one of the richest men in America. But dinner isn't at expensive restaurants. Instead, he dines at Gorat's -- a local steakhouse in Omaha, and it's always the same: a rare T-bone with a double order of hash browns and a Cherry Coke. Buffett drives himself to work each day in a gold Cadillac. He's known for being humble, courteous and personable, and it’s not uncommon for him to take a visitor to McDonald's on the way to the airport.

It's undeniable that Warren Buffett is smart. He absorbs reams of information and has an encyclopedic recall that amazes attendees at Berkshire's annual shareholder meeting -- where he takes questions without notes for several hours each year. But remarkably, his investing style is simple: buy great companies at a good price.

Part of Buffett's appeal is the charm and charisma he brings to the normally pretentious world of finance. All the while, though, he's articulating some of the most practical investing advice available to individual investors like us.
