Build off of your strengths and interests, don't ignore them ( that generally won't give results). You are looking for answers, but you should also be looking for the correct questions. It sounds like you have come to some quite profound conclusions about what you want out of life, which is great!
Like the Moog asked, what sort of greatness are you interested in? Everything has its associations; lets say you like spending 10 hours a day watching youtube videos. What kind of videos do you watch? Why do you like them? What do you appreciate about them? If you could spend 10 hours a day doing something more productive, what would it be? Anything related that you are interested in? What about that do you like? Why are you interested in that? I could just go on and on.
If you think you have AS, OCD, ADHD, or anything else and its keeping you from your dreams and goals ( or even making goals) or making life difficult, seek some professional help. Does your town/city have a community outreach program? Even if you don't have insurance, they can point you in the right direction. Call around, explain your situation and people will point you in the right direction. Sometimes just talking to a counselor is all you need to help sort things out.
Also, no, I don't think it sounds like AS, but it would be foolish to base a diagnosis off of such little information with such little insight. Really, try and find a psychologist or another professional to talk too, it seems like something you would really benefit from.
