Warren Buffet, the second richest man in the world who has donated $31 billion to charity, emphasizes living simply and investing for the long term. He still lives in the same house he purchased over 50 years ago, drives his own car, and does not have an entourage. His meeting with Bill Gates was supposed to last 30 minutes but ended up being 10 hours, with Gates becoming a devoted follower of Buffet's philosophy. Buffet advises focusing on bettering yourself through education and saving, avoiding unnecessary purchases and debt, and spending on others who are truly in need.
