Nroug7: I Don't want to make any contributions to humanity's science, evolution or technology. All i need is a decent job and enough to live comfortably, as an observer.
You don't have to become a famous changer of the world in some way to contribute to the world and persons you hold dear around you. That itself is a worthy goal and who knows what life may bring otherwise. Steve Jobs began just wanting to make a really cool computer. He never could have imagined working in a garage at the start where it would lead in time.
You are telling me you think you are brilliant if I understand you correctly but then I see you seeming to shy away from the idea of pursuing excellence when I challenge you to go prove it and earn a 4.0 GPA at a good school. Am I understanding correctly or I am missing something here?
As for the program to prepare you for university I am unfamiliar with that being from the United States but it sounds fine from what you described if it offers you an opportunity to prove to a university that they should allow you to study there. Whatever works sounds good to me as far as getting yourself into college goes.
Once there, the only way I can imagine you being bored is if you have a medical problem causing it or you are being lazy. I already gave you the free lunch lecture so I won't repeat it. If you think it might be possible something medical is playing a role you really should see a doctor and rule that out. If you feel certain that is not an issue and people close to you who's opinions you trust would tend to agree then I think you just need to draw from within and motivate yourself, etc. Nobody can do that for you or offer you any easy way to do that.
