I've been a dabbler in a number of martial arts. When I was a child, I checked out books from the library and tried to perform the techniques from there (I think I still have my paperback copy of Bruce Tegner's Karate somewhere in my childhood home). In middle school and high school, my mother signed me up for Chuck Norris Tang Soo Do (now named Chun Kuk Do) for four years. I have since dabbled in Aikido, Tae Kwan Do, Jujitsu, Escrima, Bujinkan, Capoeira, and various forms of Western weapon training.
I've never achieved mastery in any style (and, in fact, I've stopped even testing for belts for the most part, as it's no longer a goal for me), but I enjoy the concepts of martial arts even as I find myself unable to put sufficient effort into their practice to become any good at them.
