I don't think you'll take this advice (I wouldn't at your age) but please consider talking to a professional therapist. As someone that's started many businesses the reality is the vast majority fail. If your mindset is "my existence makes no sense" working under someone else you're going to miss out on all the things that make your 20's great - dating, friends, travel, etc. Not to mention you'll be more successful in business if you have a fulfilling life outside of work. Be careful.
