Dude, if you want to go into a industry where you will be making less than the guy that fixes your faucet then welcome. You will be going to spend at least 20K-100K for college and another 40K for flight trainng just so you can hope to make 70K by the time your a 10 year pilot and with no job security at all. I would spend the next 3 years because you can't get the license at your age anyways, to see how the industry is going and weather you are willing to do the sacrfice for little chance of making it at a nice airline.

Go join a club or something and find out about other occupations it's not good to think just about flying. I knew that I always wanted to fly but in high school I never though about it much, I joined the law club and the medical club and only after I learned about other occupations and found that I didn't see myself spending a life as a lawyer behind a desk or doing the stressful job of a doctor did I go back to flying.
