Warren Buffett, the world's second richest man who has donated $31 billion to charity, was interviewed for one hour on CNBC. Some interesting aspects of his life are that he bought his first stock at age 11, still lives in the same modest house he purchased over 50 years ago, and drives himself instead of using a private jet or having a security detail. His advice is to avoid debt, invest in yourself through education, follow your passions over brand names or peer pressure, and appreciate what you have rather than constantly seeking more.
