You guys will totally make fun of me for this response. Oh well.
I started BJJ because the one and only episode of Fight Quest on the Discovery Channel I've ever seen in my whole life was the episode about Brazilian Jiu-Jitsu. And I thought to myself, "Ya know, that looks kinda cool." Plus I was working at a job where the possibility of assault was high, so I figured it might be a good form of self-defense. I bought a book about jiu-jitsu first (Brazilian Jiu-Jitsu: Theory and Technique, by Renzo, Royler, and Kid Peligro) and read up on it. Then I surfed the web for schools close to my house and finally got up the nerve to call an instructor, who actually found a gym even closer for me. Another phone call and a nervous drive later, I walked into my first BJJ class. The rest, as they say, is history.
Before that, I was a total nerd with no physical activity. Now I have a badass goatee and a short, clipper-cut haircut.
I lift weights. I run. I've dropped 20 pounds and eat healthy for the first time in my life (well, most of the time). I love anything Acai. I started watching UFC and WEC for the first time back then and got stoked when I saw stuff I was doing in class. For the first time, I began to understand that "fighting stuff." I am embarrassed to say, I thought it was kind of barbaric back then before I came to understand it. Now, I get offended when people talk badly about any MMA athletics, and I try to educate others. I began training standup and other disciplines ... muay thai, boxing, judo, karate, and wrestling. I've formed a good overall personal set of self-defense skills that work for me (I will never be a competitive fighter or anything). I even read a few MMA magazines when I make it to the newsstand. And now, Sherdoggers, I am here among the rest of the addicts. I really like the other disciplines, but BJJ is my drug and mistress.
