CescP,
I'll cut straight to the chase...
I have a background in career development and have worked closely with many budding aviators of your age.
To suceed in professional aviation you need one of two things (or ideally both of them)
One, an almost fanatical commitment to succeed. A commitment that will override all else...not just sport, but social life, family life etc.
Two, a great deal of money.
If you have both great, if not you need plenty of one or the other.
You will also need a solid aptitude and a healthy body.
Might I suggest you tick off the following before proceeding to far with your plans:
Approved aptitude tests (GAPAN)
A full medical (CAA approved)
Five hours flying lessons (most schools will do a starter pack of some form)
Two of three school visits to see what's involved.
If you don't have the time or the money for the above, you might want a re-think.
