Power
You're skating around at top speeds, hurling yourself into the air like a samurai warrior, wearing what are basically a pair of uber-sharp knives with gnarly toe picks on your feet. If that doesn't make you feel powerful, what will?
Thousands of people around the world look up to you for being able to do something that very few can. If you really hit the big time, you'll embody that winning combination that sponsors and advertisers love—athleticism, grace, and a whole bunch of talent. Once you find yourself on a box of Wheaties, you'll be inspiring millions of young athletes.
So that's pretty powerful stuff, but really only in the metaphorical sense. When it comes to actual power—the commanding, demanding, ruthless politician-type power—you won't find much of that. But maybe that's not a bad thing.
