I trained a little over a year in BJJ and was probably about 6 weeks away from getting my blue belt. I loved it, but I had to give it up when my job had me working Tuesdays/Thursdays during season when the snowbirds came down, and Tuesdays and Thursdays were the only days we trained. The thing I didn't like was that it was a very small group of us, and rolling with the same people over and over got pretty old. It was always exciting when somebody new came, but it was either a complete new guy that was way out of shape and went into cardiac arrest during the warm up, or a really good brown belt that showed up from time to time that kind of just helped us out.
