Warren Buffet, the second richest man in the world who has donated $31 billion to charity, advocates for a simple lifestyle. He still lives in the same small house he purchased over 50 years ago, drives his own car, and does not have security or attend high society events. Despite owning Berkshire Hathaway, one of the largest companies in the world, he communicates with CEOs through only one annual letter and two clear rules focused on not losing shareholder money. His advice is to invest in yourself through starting businesses, avoid unnecessary purchases, and enjoy a debt-free life focused on helping others.
