I doubt that your going to blow up. Good kids at PC come a dime a dozen. All 4 5's isn't gonna get you very far either. try more like all 4 9's. So by blow up you mean you would probably just end up on someone's flow team. and you're 18, probably too old to make skiing a life career. hate to tell it how it is, but that is how it is.
HOWEVER, my roommate this year was a mormon. And he made me absolutely hate the mormon religion. I mean seriously, don't you guys have anything about NOT imposing your religion on other people? So because if that, I think that you should ski and do missions when you are older. Two years is a long time out of your life that you won't get back.
So if decide to ski, ski for fun, but to "blow up" is gonna be really hard.
If you go to the land of the talking animals, I suggest you wear a helmet when you ride your bicycle.
