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.
