Most people are brought up to believe that going to school, getting good grades, working really hard and getting a good job are the steps you need to take to become successful in today's world. Education certainly provides benefits towards your career, but it also isn't necessary all of the time. There are plenty of entrepreneurs who were college dropouts, but still managed to achieve a great deal. I have compiled a list of 10 very successful businessmen who achieved such immense greatness without earning a college degree.

1. Mark Zuckerberg

Zuckerberg dropped out of Harvard in 2004 during his sophomore year to work on Facebook full-time. His net worth is estimated around $55.7 billion USD.

2. Ray Kroc

Ray Kroc bought McDonalds in 1961 for $2.7million and turned it into the multi-billion dollar company we know today. He had previously worked as a salesman and never even went to school. With a net worth of $600 million USD at the time of his death in 1984. That's the same as $1.4 billion USD after adjusting for inflation.

3. Evan Williams
