I concur with the above... In order to succeed you have to focus on the next step. Right now, it wouldn't serve any purpose to read a NATOPS manual. In order to fly anything in the Navy you first have to accomplish the following IN ORDER:
Graduate High School
Apply for a College/University
Get accepted to a College/University
Work extra hard at College/University and get good grades
Graduate College
Apply for a commissioning program (if ROTC/Academy will be simultaneous with college)
Get accepted in commissioning program
Work hard in commissioning program
Earn Commission/Become an officer
Work hard in API
Graduate API
Work hard in Primary <-This is where you should take your first look at a NATOPS
Finish Primary
When looked at as a whole, it seems insurmountable, at least that's how it felt to me when I was where you are. But you eat an elephant one bite at a time. This is a set of hoops you need to jump through consecutively. You won't make it very far if you are spending 3 hours a day in college studying a T-34 NATOPS while the next step isn't getting done (getting good grades in college as to make yourself competitive for the flight program). Accomplish these tasks by devoting all of your attention to the next step, all the while being aware of the following step.
Hope the jibber jabber makes sense. Good on you for figuring out what you want in life so early and aggressively pursuing it. You'll find that this forum will be a huge resource along the path. Practically every question you will have has been asked and answered ad nauseum, so use the search function.
