What influence you have on other people is probably not a significant factor on most peoples decisions in life.
I spend 3/4 of my time doing things that influence other people's lives. On top of that, I spend half my ski time teaching kids to ski. Those are important to my life, but they are certainly not all of my life.
Skiing is just pleasure? If it were "just pleasure", I might be content the rest of the time to ride the lifts and ski groomers. Instead I spend much of my free time climbing in the backcountry. I don't do it to influence people. I do it because it keeps me in shape, it gives me mental and physical challenges. I do it because I am a skier. I ski with my girlfriend and with my son. I ski with my friends. As much as I enjoy the pleasure of skiing, I enjoying seeing them happy even more.
Right now I am working my ass off, trying to recover from a injury. I have been in PT for 4 months now, with at least 2 more painful months to go. I run 3 days a week, and do weight training 3 days a week, on top of the daily rehab exercises. I WILL be back. Not because of any influence my skiing has on the world, but because it is healthy, it is a way to push myself, it is a way to spend time with my friends.
I'm sorry you're so jaded.
Go book a trip to Alaska for your powder-cravings without your family and regardless of which friends can keep up with you and tell me it's something other than self-devoted pleasure.
Perhaps I mispoke in the past stating that; "Skiing is pleasure." Skiing, as pointed out above, is and can clearly be a direction to things other than pleasure.
It does, however, reach a point where the motives change. And all you aspire to can become convoluted into an egocentric direction. Aspiring to win a world-championship has very little to do with what you choose for your interaction with your family. Pursuing being number 1 is pretty selfish. And I apologize for asserting that all others may define skiing as I do. That was selfish.
