Investor and philanthropist Warren Buffett is widely regarded as one of the wealthiest and most influential people in the world. Referred to as the "Oracle of Omaha" for his prowess in business, he is also known for being frugal despite his incredible wealth. Buffet still lives in the same house he bought after getting married in 1952. His foray into investing began when he bought his first stock shares at 11 years old. That experience taught him a valuable lesson that he continues to adhere to when in comes to investing: be patient. Today, Buffett's net worth is close to $67 billion, according to Forbes.
