Get a job an sort it out for a little while. I've seen too many kids like yourself come into the service as a last resort or what they think is a last resort. Coming into the military should be a choice, you have options.
First some definitions. The term "Kid" is used by personnel in the Navy to describe junior personnel requiring guidance on specific issues. It is generally not intended as argumentative or derogatory.
I'm not going to speak for everyone here, so take this from me to you. As I've said before, I've seen a lot of kids in your position. You feel like you need to make a decision and want all the advice you can get. It is an understandably pivotal point in your life. Unfortunately you have smug little answers to people trying to help you out. Help that you "googled" and now smite because you have thin skin and are a know it all teenager. This is not a crime, many of us on this forum have been that kid before, it is curable. I've been teaching kids like you for years and never tire of giving advice.
Here is the advice. If you don't want what the military is offering you...don't sign the papers. If your "Collage" application isn't working, take a semester out of the game, do something you will never forget, be it good or bad. Meaning, go on a trip that is awesome or lay concrete for a summer. Neither you will ever forget for totally opposite reasons.
Being in the Military Service requires sacrifice. As a new recruit, yes you will have the option to go to school. It isn't easy, but it can be done. Prior to this know that the more junior the rank, the less opportunity you may have based on your work requirements. As you progress in rank and time in service, you have more accountability and responsibility but by that point you will have learned better time management skills allowing you to juggle your schedule more effectively.
I can tell you that being any sort of Aircrewman takes total commitment. No half assed "this is a stepping stone stuff" will be tolerated, especially in Schools Command. It is also a choice and the people who don't really want to be there will find themselves reassigned.
Take a hard look at what you really want and don't let anyone talk you out of it. If it's becoming a Naval Officer, go to school; if it's becoming an Aircrewman, sign the enlistment contract, roll the dice and we'll see you in the Fleet.
