Two years is a long time... but you should be stoked to spend time experiencing (hopefully not invading or imposing upon) a new culture in a pretty badass place that you might not otherwise get a chance to travel.
No offense... but you're not on your way to "blow up" if you just learned all 4 5's... that's sick and all... I can't spin SwRight for shit... but don't feel like you're missing out on anything except fun days on the snow with your friends... which, trust me, I know can be a hard thing to do without!
Learn how to surf:

Or kiteboard (if you can afford that shit)
Bring a skate deck or two (depending on where you’ll be… it’s not all lemurs and jungle)
Meet new interesting people.
Learn a new language.
Check out the BADASS wildlife that exists nowhere else in the world...
Learn something about photography and take some sick travel pictures.
Bring a stack of ski mags (not only will they get you through your pow/park-less time but people who haven’t seen skiing won’t understand unless you show them pictures… they probably still won’t totally get it.. but they’ll be interested)… have your mom send you all the videos next fall… and go do something sick that you’ll always regret missing if you don’t!
Just my thoughts...
