I have thought about this a lot of late and karate has changed my life so dramatically it would be hard to imagine life without it. The only other discipline which I was never terribly disciplined at was music, so I guess if I didn't have karate I would be doing more music than I am now. I have only ever trained in 2 styles of karate and maybe I would have tried something like aikido or kung fu or kendo I guess. I have been thinking about doing that soon anyway just for a bit of extra knowledge outside my current sphere.
