EStrike101: I suggest you go 1 step at the time. At your age, I was probably as eager as you to fly the Hornet. 10 years later, I'm still in training and yes, a lot of people washed out and no, not everybody that wanted jets got it. Saying you will fly the Hornet at your stage is a very bold statement in my opinion!
As to what's the best thing to fly, it depends on preference.
