Warren Buffet, the second richest man in the world who has donated $31 billion to charity, believes in living simply and investing wisely. He bought his first stock at age 11, still lives in the same house he purchased over 50 years ago, and drives himself instead of using a private jet or security. Buffet meets with the CEOs of his companies only once a year to give goals, and advises living within your means, investing in yourself through education, and not worrying about brand names or what others think.
