Find something cool, something that interests you, something you want to do. There will be time to change the world later; you clearly have the ambition and I'm guessing you have the talent also. For now, I think it makes sense to just pick something, probably something small, and do it. Whatever you choose, you will learn something -- and you will probably learn something that you weren't expecting! When you are 18, I definitely recommend you attend as good of a university as you can. Good luck to you!
