I don't know if you want to base your ENTIRE career around the ability to be able to ski. Yes, you want to follow your passion. If you're doing what you want every day for the rest of your life, you never work another day in your life. But from what you just stated, you're a smart kid. I suggest finding an additional academic passion. Then pursue a career that allows you to live around a mountain, and get enough days in during the season, but also allows for a comfortable living(which I know is exactly what you are asking by posting this thread). Honestly, MANY jobs would allow you to do that, you just need to find one in an area around a mountain. I would not try getting a resort job as a career. I know people are content with it, but I would not be one of those people. I LOVE skiing, and I've put a lot of thought into doing something that'll allow me to continue skiing the rest of my life, hopefully more frequently than in my youth. But more importantly, I want my future family to be able to live comfortably, introduce my future kids to skiing at a young age, have them ski to their hearts content as they grow up. Without a decent career, I know that last goal I won't be able to achieve.
As I went through high school and college I've found that I LOVE the sciences, and previous life experiences have led me to know I positively want to be in healthcare. I'm applying to medical school this summer, and hopefully am able to make it into a medical profession at some point in my life. I know however, that this will be extremely limiting in my available time, but I'm hoping to find a job eventually in a state with mountains, ski more than I do currently(I grew up and am living in Iowa currently, so it's not hard to top), AND provide my family a comfortable life. Just my 2 cents, a very long winded reply, but it summarizes my thoughts on the subject well.
