For me it's surfing. I've been surfing intermittently since my dad taught me how at age seven. I've always owned my own boards, but never really got out on the water enough to get good at it. Every time I do get out there though, I love it. I love the peacefulness, the thrill, being on the water. And every time I do it I think, "I should do this more. This is something I want to get good at." But for whatever reason it falls by the wayside. Anyway, one of these days I'm gonna take the time to improve my surfing while I still have my health and fitness. I think it would be one of life's great regrets if I didn't.
