I want to Drop out of College

I am so sick and tired of going to school. I wanted to be a doctor and I am in my junior year of college. But as time goes on I realized my heart is not in it anymore. I do not want to work for someone and I actually want to start my own business. I see so many people making 6-7 figures and never went to college they just started their own business. Am I wrong for waiting this ? Would you drop out of school to actually do want your heart wants ? Are should I stay in school ? Has anyone stop going to college and still became successful?
