"I don't sleep. I wait. I sleep in cars and on couches. I sleep when I can, but when I can't sleep, I just don't, so I figure there's a higher calling keeping me on point that night."

Sometimes I train in the middle of the night, all on my own. Can't sleep, don't want to sleep, get up, go to the gym, work. This is early for me, being here at half ten in the morning, this is really early, and I'm only here because I screwed up yesterday and kept you hanging around. Other times I'll call up my wrestling coach, or my jiu jitsu coach, or my deep-tissue guy, and want to really focus on one part of what I do. I train in all these different disciplines.
