Inspired, nope, told more like! A director in the company I worked for was mates with a local Karate instructor on Gardiner street, and all the young lads in the company were rounded up and told to take up Karate. I stuck with it for a couple of years and loved it at the time, but only got inspired after I'd already been there for a few months. I did like the opening scene from the Karate Kid though, where the little dude gets attacked by all the beefy dudes, and it turns out not only are there more of them, and they're bigger, but they're also all Karate heads and beat the living crap out of him. Priceless!
Wasn't particularly inspired to take up tai chi chuan either, more a bit drunk on the way home from the pub with the GF and convinced her it would be a few laughs and a bit of relaxation. A few laughs it was, with wrestling thrown in on the first night, and full contact sparring a couple of weeks later. Relaxing didn't kick in until we got to the pub after class. To be fair, the GF kept it up for six months, but it wasn't quite what she'd signed up for. I loved it, and while I don't train nearly enough any more, still do.
I tend to be inspired by people who are good at what they do, particularly those that are much better than me (most of 'em), and this more often than not happens on the mats. I also get inspired by the sheer effort some people put in, and their willingness to carry a fight to someone much bigger and more skilled than they are, in the full belief that they will totally destroy their opponent. I'm further inspired on the those occasions it works for them
