Bill Gates once told his professors at Harvard that he would be a millionaire by the age of 30. As it turned out, he became a billionaire at 31.
Despite an early interest in computer programming, Gates initially studied law when he enrolled at Harvard in 1973. But his interests would continue to be drawn to the computer screen rather than his legal studies. He would leave Harvard two years later to work with longtime friend Paul Allen on their first operating system under the "Micro-Soft" name.
There's a lot you can learn from his experience, so to get started, here are 50 Bill Gates quotes on life, investing and the future of technology and business.
