Pred:
Might I suggest that you try to find a kindly flight instructor who would be willing to take you under his/her wing and provide some mentoring. He could help by outlining the processes and type of learning you will have to undertake.
Perhaps joining a local flying club near your home would help. Or just hanging out at a local airport where old guys gather to fly a bit, work on their airplanes, chat a bit, and spit occasionally.
If you act interested in all aspects of aviation you'll find folks willing to help you.
Meanwhile, work at your schoolwork -- math and science especially.
