Going to college does not guarantee success in starting a business. There are too many examples to name of entrepreneurs dropping out of college to start their successful businesses. However, studies at the Kauffman Foundation find that the age range of most founders is from 35-45 years of age after plenty of experience in the workplace. They state one can study entrepreneurship while in school, see a variety of courses and experiences, and consider higher education instead of quitting school to start a company.
Still, sometimes great entrepreneurs are born, and staying in college is a waste of time learning things everyone else already knows. These are the ones you hear about later.
