If there's any solace for you, there are plenty of similarly brilliant kids as you that did stay in school to try to get that 'college' experience, and still are unsatisfied with themselves and feel out of place. Think about if you were in that normal streamlined path in college, would your personality and innate nature really do a 180? Highly doubt it, even though most people think they can exercise a locus of control and that external circumstances can change their deep inner character. There's a reason why you gravitated towards leaving school and being a young genius and working early. You live a unique (and impressive) life. Try to live your life out like a movie and don't look back at the what ifs. You're 20 too, haha. You're a baby. Your future is fucking unscripted. Don't worry about any of that shit. Your life is just starting.
