People study martial arts for many reasons, sometimes all the wrong reasons. For example, I have had potential students come to my dojo with a belligerent and cocky attitude. When I ask why they want to study my art, their response has indicated to me that their goal is to learn to fight, which is the antithesis of the philosophy I hope to instill: I want them to know how to defend themselves if necessary, but to avoid fighting whenever possible because they will have nothing to prove by fighting.
It's amazing because people come up to me and say, 'Chuck, you're the luckiest guy in the world to be a world karate champion and a movie and TV star.' When they say this to me, I kind of smile because luck had nothing to do with it; God had everything to do with it.
