Congrts on getting started, that's the tough part. LOL Learning BJJ is like learning to play chess. You can get taught the moves in a day but you'll spend the rest of your life learning how to put them together.
I'd be willing to bet everybody here felt really akward their first time out. Just keep rolling and drill the basics like crazy. Just like in chess you have to be working 2-3 moves ahead, cause if you wait till you see it, it might not be there when you actually go for it. lol
