Well, I did judo until september. I was getting borded with every single day of training, and I hated competitions because they mean to lose an entire saturday or sunday just for a max of four minutes matches. Therefore, I left judo before getting the brown belt.
From september I began with karate and I found it's an unlimited ocean of techniques and posibilities, some bushido philosophy and a great way of self-improvement with intensive trainings. It's not easy, and it can take you a lot of time to master some basic things like striking WELL, but I'm feeling it's worth the effort. About competitions, they're not so important, and the most faithful to karate-do styles, like Shotokan, don't even have competitions, because according to karate-do philosophy, it's a way of self-improvement, not a fighting art.
I think it's clear what's my favorite sport
EDIT: Sport on IMVU? Oh, crap! But I wont delete all this stuff, it took me too much time -.-"
