What does it mean when a person says "I'm a martial artist"?  
Does it mean "I'm a badass"?  Does it mean "I'm a better person than you"?
Of course not.
Recently, I posted a meme on my Facebook page that featured a quote by Gitchin Funikoshi.  Now, while I may not exactly be a fan of Funikoshi, I believe that the quote summed up up what a martial artist is - a person who uses the discipline he gains from practicing the art to become a person who is better than they were the day before.
