P.P.......
First , at the current age of 14, I would think you're familiar with computer forums. There is a Private Flying and Wannabee forum on this site where your inquiry would be better (and shortly will be) sited.
Regarding licenses......to be a paid pilot, you will need at least a Commercial license with an instrument rating - it would be best to also have your multi-engine rating first as well - but, things are always changing in the 'regulatory' arena, so these requirements may increase in the near future.
As for costs, in general, it's less expensive to learn to fly in America. BUT....AVOID THE PILOT MILLS!!! (Just look in the private flying forum for information about this).
Costs, of course, vary....and are based on the number of hours it takes you to complete each license course. If you train in America, you should plan on spending approximately $4-5,000 USD for your first license (Private Pilot-Single Engine Land, Airplane), and that's just for the airplane rental and instructor.....MUCH more if you want to fly helicopters.
Hope this information gives you a start....best of luck with your future plans! Do NOT let ANYONE talk you out of your dreams!! If this is TRULY what you want to do....then GO for it!
