I've been a licensed skydiver for over a decade and jump a lot during spring-autumn. That is my warm weather happy place (I jump enough during winter to stay current, but I dial it back a fair bit), plus wind tunnel training. I also do track days on my motorcycle, so I have no dearth of places to get excitement.
But skiing is my first love, however, and I'm at my happiest when I'm on the mountain either by myself or with one or two close friends of a similar skill level. To get up before sunrise and get there early so I have first chair, and be the first through the new powder that fell overnight and feel really in touch with the mountain and the snow… nothing quite like it. I'm just as happy cruising around on the groomers and relaxing as I am pushing myself to the edge of the envelope in a bowl where an error in judgment or letting my ambition overpower my talent means a spectacular crash. If I had any sense for religion, skiing would be church.
In the sky or on the snow, the rest of life doesn't matter. I don't think about my job, my family, my friends, my bills, my mortality, my health, movies, sex, money, pets, gadgets, cars, politics, or anything else good or bad. These places are why I live.
Edited to add: and really, this has not been a spectacular year for me and I've been looking forward to ski season a lot to help with that. So to potentially have that taken away from me, along with not being able to count on the car which would help with day to day happiness… it's very first-world stress, but it's still stress. The good news, though, is that I was able to walk without pain (under controlled circumstances) over the last couple of days, and today I successfully drove to work, so the knee is on the mend. All hope is not lost.
