From a personal sand point, I did it the old fashion way, HS, Navy, dive into the work force, finally find a job I like, stay there 30 years.
My sons, well I can tell you some stuff there! I have two, 26, and 24 now. Both have Bachelors. The oldest went to a vocational school with "Electronics" as his vocation (it was the closest thing to computers then). After HS he went to college and got a bachelors in Computer Science. Went to work in the IT dept at a security software company. He is now the lead animated scrip writer for the software company.
My youngest went to the same vocational school with "Culinary" as his vocation (his grandfather and I both cook). After 4 horrible years in that department He graduated with honors and went to college with a double major of Art and Music. He dropped art after the first year and music after the third. Looking at what he had for credits, he decided he could get a bachelors in psychology if he set his "mind" to it.

He did and got it. That was 2 years ago. He works for Gamestop, and has irons in 6 or 7 fires because he STILL doesn't know what he wants.
The point is I have two talented and very bright sons. Both THOUGHT they knew what they wanted in HS, one seems to have been right. Don't lock yourself into any one path. If there is a will, there IS a way. We put two kids through college and as I said, I did it the old fashion way. The youngest wanted to try getting into videogame art and stories (he has a portfolio that many would kill for) we helped get him into a school in Washington outside Seattle. The work load was too much WITH a job and it wasn't like what he thought it would be. So he came home. But he went for it. If you want to fly, GO FOR IT !!! Get a job after school and stash EVERY penny then when its time to pay for lessons, you have a big chunk all taken care of. If you don't want to work after school for it, then I guess you really don't want to fly that bad. Thats where that "will" part comes in

The point is, not everyone KNOWS what they want to be when they grow up.....other than rich

Stop thinking about starting pay on a job you haven't even looked into, nor are you qualified for. If it's the job you want the money won't be that important. If your looking for the job because of the money, chances are you could get it and be miserable at work. Remember, your at work 40% of your day and you sleep 30% and the other 30% is chores/eating/and play time. Do you want to be miserable most of the day?
Your young, try things. Lots of airports have free/cheap first lessons. Try it out, you may like it, or you may LOVE it, then you'll know. Try other things as well. Volunteer at a vets or pet store to clean up if your interested in animals. Volunteer at a hospital or old folks home if you might be interested in care giving. Don't sell yourself short, any thing is possible. It just depends on how much work YOUR willing to put into it.
Good Luck!
