Career Path

I just turned 15 and have been so interested in aviation all my life and after some careful consideration I’ve decided to strive for a career as a pilot. I’ve taken one year of high school so far and was wondering what classes to take to support my future career. My hs also doesn’t have many aviation related classes, will it make it harder for me to become a pilot? When should I start flying or taking flight school? What’s the process?.. I’m very new to this and unfamiliar with the process but I’m eager to learn and put in ALL the effort. :)
