This is a tough one for sure. I've faced the same dilemma, but to me it was easy because I actually thought handball (my #1 sport) was more fun than skiing. Well, maybe not more fun in every aspect, but it gives me more satisfaction.
You know you are good at football. How good are you at skiing? what is your mindset? Will you get more satisfaction out of working your ass off in order to become a great QB or out of living the ski bum life?
Unless you think you're on the verge of breaking through big time in skiing, I'd go with football (unless you've started hating it by now, of course). If you take a year or two off from football to go skiing, your football career is gone. Poof!
But if you go play football for a few years you'll still be able to come back to skiing and have as much (or more) fun than ever.
To me, skiing is the kind of activity that gives me pleasure just from doing it. In sports that I train a lot in I get my satisfaction from knowing I'm good at them. Nothing wrong with that. If I had decided to quit handball in favor of skiing just as things were starting to go well for me I would have always wondered what I could've become if I'd walked that extra mile. That would have eaten me up inside.
Don't do anything because you feel that you have an obligation to others to do this or that. Make scenario analysis and analyze the different outcomes.
Picture yourself in 3 years if you go with skiing. What will you feel like/what are your options if it works out? What if it doesn't?
