I listened to an interesting episode of This American Life which posed the question, "If you could choose one superpower, what would it be?"
Surprisingly, the power of flight and invisibility come up more times than any other superpower. Most times, people would use invisibility for more nefarious purposes and the power of flight tended to be something people would use to impress others or have a good time.
Therefore, whatever power people chose tended to say something about their character. What would you choose if you could? Would you choose something to better mankind or something that furthered your own purposes? I actually used to play this game a lot with my friends and co-workers. My personal choice would be to be able to speak any language in order to communicate with any person or animal. I thought it would be cool to go anywhere in the world and be able to talk with someone.
One's choice in a martial art is kind of the same thing. Why was that particular art chosen? Was it chosen for nefarious purposes, to show off, to hurt others, to impress people or to be cool? Whatever art form you choose, please choose it for the right reasons because it says a lot about you as a person.
