There is no glory in dropping out. "Dropouts" are not some super-class of people who are destined to save America. It's just something I had to do in order to have the time to start the company I wanted to start.
Addendum: The best dropouts are those who would do well in school anyway. I've had people tell me "I'm barely passing in school because the stuff doesn't interest me. I'll drop out and I do what I want to do". There are 1001 things about running a company that are more boring than your school homework. If you can't do well when someone gives you a curriculum and is helping you, you don't stand a chance keeping yourself motivated enough to start a company.
