I've raised millions for my startups multiple times. Some of my pursuits have worked out but most have not. I don't regret dropping out but it is definitely held against me. Prepare for many people that needed to goto college to get a foot in the door to pre judge you and you may even miss opportunities to get in front of important people because of that prejudice. I'm lucky I had extraordinary circumstances which helps people psychologically get over their preconceptions of a dropout. To most that are thinking of dropping out I advise them not to.
