It all depends.
Sometime's I think, - "I ski like a God, the world is blessed to gaze upon this perfection". (Yup - legend in my own mind).
Other times I think: "I ski like crap. I hope nobody's watching - especially females".
Some days you're in the "zone" and if flows, other days you feel like you never could ski.
It also depends upon the hill. At smaller hills I've been "the King" (the top percent or two). At Alta, Snowbird or Jackson Hole, I discovered you'd better have your game face on. There, I'm lucky to make the top quarter.
Finally, age is a factor. In younger days, I used to consider myself an "expert" - there's a frequently abused term.
Now, at age 50 (but still adorable), I consider myself "advanced". "Expert" is an elite category that we'd all love to put ourselves in. But few truly qualify.
One learns to accept limits with the years. A sense of adventure and beauty remain. But, respect for physical change is required by Nature - or you become a casualty of Natural Selection.
Perhaps I've become more humble with maturity. Who wudda thunk?
P.S. The exception was Jim McConkey (Shane McConkey's father), who used run the ski-school at Whistler. This man broke all the rules. I skied with him in his 50's, and there wasn't a single buck on the mountain that could match the gonzo pace he set, and the insane lines and cliffs he'd tackle. The man had no respect for age or fear.
