This list made me chuckle a bit...I remember reading it a while back, when it was first posted, but I went back and re-read it again. There is someone at my gym that represents almost all of these different personas. When I sent it out to some of the guys I train with, one of them labeled everyone. I got labeled as the humble ****you up guy, although that's not the way I view myself. At times, I exhibit traits of many of these different personas. But I think I'm a new breed (and probably not the only one). Kind of the opposite of the no-responsibility guy. I have a deep-seeded passion for BJJ, and would eat, breathe, and sleep it--if I had the time. But, I have to juggle work, a wife (who is moderately not thrilled with my devotion to BJJ), and two young kids with all of their activities. And while I wouldn't trade any of this for anything in the world, it seriously hinders my training time. I manage to eak out 1, maybe 2 days of training a week...so, I compensate. When I can't actually be on the mats, I spend a lot of time thinking about technique, game plans, etc....I have most of my instructional DVD's copied to my Ipod, so that I can carry them with me and review them when I have a few minutes of downtime. I kind of envy the no-responsibility guy at times, and wish that I had started when I was younger and could devote the time to train twice a day, 5-6 days a week. But, I'm happy to slowly progress and enjoy my hobby. I don't have any aspirations of becoming the next world champion or the next ultimate fighter. Just happy to continue to train and learn, and am always excited when I pick up something new to add to my game.
I thought of one other personality type (one of the guys that I train with)....the anti-gi guy. This is the guy who acts as if putting on a gi will cause him to immediately have a severe allergic reaction. He's a decent grappler without the gi, but his absolute refusal to participate in anything involving the gi has somewhat limited his game. He's perfectly fine for you to enter his no-gi world, but it doesn't work the other way around. He likes to justify this by commenting on how impractical the gi is in an actual street fight (which apparently he's been anticipating for many years now, but just hasn't happed yet, and which of course is the ONLY reason anyone would train BJJ). This guy is also closely related to the heel-hook hero.
BTW, don't mean this to start a gi vs. no-gi debate, which has already been beaten to death on this and other forums. Personally, I like to train both...just thought I'd add this personality to the list, since I know several people with this syndrome.
