First, I should just let you know that you have you're priorities in order, and you're being really thoughtful about the situation so props.
I felt the same way last year. I'm nineteen now, but I was for a while feeling pretty intent on avoiding college. What I came to realize after discussing things with my dad for a while, is that a university degree now doesn't stop you from doing anything else. Honestly it's a nice cushion to get your feet underneith yourself, get a boost in the job market, and most importantly, find and follow your passions. I feel identical to you, I'm in an arts and science program, I'm studying biology, but I don't see myself being a biologist. I'm doing it because I'm interested in the subject. I have a long life ahead of me, and I think the key element you're missing here is scale.
You don't have to be funneled into the job market. A great example is my dad. Got his undergraduate degree, graduated, got his pilots license, bought a motorcycle, drove around america for two years, worked for another year, headed to nepal and southeast asia for another year, and eventually landed up in architecture school after contemplating his fate for a very long and adventurous time. His twenties was filled with everything I could ever want, and by the time he was thirty something, he had seen the world, had most of the insane experiences youth can possibly provide, earned an undergraduate and two masters, and found his wife. He didn't start his proffessional degree till later, and you don't have to. I don't see the point of rushing into societal slavery. He's a successful Cornell professor now.
It's true that if you start you're career earlier you'll find your way up the ladder faster. But the truth is, life isn't about what society tells us success is defined by. You need to decide on your own, just make sure it's a sound decision.
There is literally nothing wrong with what you're thinking, but here's something to think about. College is an incredible time. If you're not an idiot, You learn a lot of life lessons, meet and network with a ton of people, have some of the most epic experiences, and satisfy your intellectual curiousities to your hearts content (just make sure you go to a school where you can do all that, I suggest mcgill from experience). After a year, I can say I'm glad I'm not ski bumming ,because from the people I met with, I cofounded a non profit media organization, I have friends all over the world I can visit and travel with, I'm more mature than I ever could have been without the entire experience, and I'm figuring out what I'm really passionate about in life, so when I graduate I feel ready to hit the ground running and tackle whatever I have the means to do.
A year off can be a really good idea, a lot of people do it. If you're in no rush and you're slated to have an advantage, I would say give it a shot. Although college is awesome, you don't want to regret not pursuing something as epic as getting involved in the ski industry. If I could be skiing professionally I probably would, I'm sure anyone here would agree. Spend a year around, if something clicks, then follow through, if it doesn't, then you know college is going to be great. So that's my advice.
RIP Friends. That show was there for me through the times I watched from the couch, to the tougher times where I watched from a loveseat or even the floor.
