Warren Buffett, the second richest man in the world who has donated $31 billion to charity, was interviewed for one hour on CNBC. Some interesting aspects about his life are that he bought his first stock at age 11, still lives in the same small house he bought over 50 years ago, and gives his CEOs just two rules: do not lose shareholders' money and do not forget the first rule. His advice to young people is to avoid debt, invest in yourself, and appreciate what you have rather than chasing brand names or status.
