Theres actually a lot more to life than skiing, I personally chose skiing over just about everything else, but there are literally thousands of other sports that people do along-with or instead of skiing.. There are also things outside of sports that people get their jollies from, school clubs, jobs, hobbies, video games, traveling, vacations. And I'm not even going to elaborate on any of those things, but basically skiing and ski culture are an infinitesimally small speck in the world that we happen to be a part of.
It may be what the majority of newschoolers (including myself) choses to spend all of their available time doing, but that by no means makes it the only thing in the world.
