Multi-billionaire from Omaha, Nebraska, Warren Buffett has made himself and others rich by very specific investment principles, which he has followed almost exclusively throughout his adult lifetime. As a young boy, Buffett was fascinated with numbers and money and, at a very young age, vowed to become rich, not for what riches could buy but, rather, just for the fun of accumulating money. He developed several plans for making money, to include gathering up used golf balls at the local courses in Omaha and re-selling them.
