Warren Buffet
Buffet is one of the world’s most successful investors with a personal fortune of over $90 billion. However, he’s also a great philanthropist and gives money away to many good causes. Most people assume that he lives in a super-mansion but the opposite is true. Buffet’s house will surprise everybody because it is relatively modest.

In 1958, Buffet bought his house for about $30,000. He never moved because it served his needs perfectly. This goes to show that people who enjoy simple lives find peace quickly. Occasionally, Buffet indulges in expensive purchases but he knows the best ways to manage his money (via Harvard Business Review).
