I am 14 years old, advice on becoming a personal trainer?

ok so i want to become a personal trainer when i grow up. i work out, and eat healthy all the time. my friends always ask me questions about fitness and health and i also love working out with my friends and they always ask me what exercise they should do for this and that and what machines work out what and i always answer them. They also ask me about what's healthy to eat and what's not. So i thought it out and since i love doing this i figured id be a personal trainer. but i dont know the steps to becoming a personal trainer. or like where i would have to work before helping people and ik i need to go to collage. Lke i dont know what to do for now to learn how to become one or what the steps i have to take to get to that level ect. any advice please?
