One thing I noticed that you asked, and no one has commented on yet, is that you thought that you could just go out and train and become "elite" so the military would want you. I've got zero military experience, but I'm pretty sure that you don't train FOR the military, you train IN the military. It is not a job that has many prerequisites and no prior experience is required. I once told someone that I didn't think that I had anything to offer the military, and they corrected me by pointing out that you don't bring skills to the forces, you learn skills FROM the forces. Something to keep in mind.

It would be a complete waste for you to try and go to college and try to pick a major that you think would make the military like you more.
