I hate to say it, but this is true.
I would advise skiing as much as possible where you live, and seeing how good you get.  When you graduate, if you are already making solid money, go for it as a pro skier.  Even then, I would not advise doing that, as most people don't really make much in skiing.
I would advise going to the University of Utah, or some place like that, and skiing constantly in college.  After that, if you have the opportunities, try to ski for a living.
I was a ski bum for 5 years, between college and grad school.  During college I skied about 30 days a year.  You can ski a whole lot more than that, if you want to.  I like my life now, I make good money and ski 40-45 days a year.  Next winter, I may be able to heli ski for the first time.  I would rather have a real job in Colorado, Utah, Seattle, or California(requires driving, but still possible to get 40-50 days a year) and  ski every weekend and vacations, than be a ski bum.  Don't get me wrong, I loved ski bumming, and I respect the guys who never left Tahoe, I just realized it was not for me.
You don't want your decisions now to limit you in the future.  If you decide you want to be a permanent ski bum, and work your butt off as a carpenter/contractor all summer so you can ski all winter, more power to you, that's cool.  Like I said, I decided it was not for me, but I respect people who stayed, but you don't want to commit to that now.  You should get an education, THEN decide what to do.
I hate to say it, but the type of life you want is more likely to end up with you as a 35 year old ski bum than a chest full of x-games gold.  Even if you do make it as a pro, most guys don't make much.  For every Shane McConkey/Tanner Hall/CR/Candide, there are tons of guys who absolutely ripped, and barely made anything form skiing.  Seeing yourself working your butt off to ski, and not making any money off of it, is a more likely life than driving a lambo like Jon.
I assume you are around 15, if you are thinking about going to an academy.  I would not make life limiting choices now, you may really regret them later.
