KP is exactly right. There are so many roads ahead of you that may halt your dream, but you still owe back time.
Great example, our friend played football for the AFA. He was injured, but not so bad that he could not fly. Fast forward 8 yrs as a Captain he plays squadron flag football, he gets injured again and now became DNIF. He had just signed his 3 yr committment, and it was over for him. In the end he retired out of the AFA 2 yrs ago as a full bird colonel, never having flown again in 15 yrs. because it wasn't just about flying to him.
On the flip side we have had friends who did not get promoted above major because all they ever wanted to do was fly. They never took a desk assignment, never got a masters, never did PME. His family will lose thousands of dollars every yr because of that decision.
Have the dream, but don't be so shortsighted to see just that dream. Also, what happens if you go to UPT, but they give you a UAV, are you still going to want to stay in the AF, or is it all about the jet? You need to be honest with yourself, expect the best, but be prepared for the worst. That is all I am trying to point out.
AS far as the dream being lofty so you will aspire to obtain them, that is a personal belief. I don't see flying jets being lofty (probably because Bullet did it for 21 yrs), I see it as the same type of goal as if someone said I want to be JAG. What I would say that would be lofty IMHO is the thought that you can get the military to pick up the law school bill. Lofty also would be a flight surgeon for the 22 or Air Force 1, because you really are a rarity when it comes to the military.
