I more or less randomly tripped over this documentary on skateboarding: Freeling. The video consists of a number of kids talking through what skating means to them. Not only is the movie visually stunning, but the dedication and passion of these kids is downright amazing.
Perhaps my biggest take away is this: if you haven't found something that brings you community, flow and utter joy, then you need to keep searching. Maybe it's skateboarding, maybe it's basket weaving, maybe it's programming. Who knows. But your passion is out there. And when you find it, you'll be able to sit in front of a camera and wax on like these guys do.
Enjoy! I'm off to eBay to look up prices on used skateboards for old people.
Update: Oh, and if you're a parent who's got a kid interested in skating, the above should be mandatory watching. Your child may be on to something huge here; something you may truly want to nurture.
