lately ive been getting frustrated with my training. i feel like i should be doing better, and like i know the techniques but im slow to react and i just get into worse and worse positions. bjj has always been fun to me but sometimes i go through these funks where it isn't. im a pretty competitive person, and im sure that it doesnt help, but sometimes i just need to calm down and not take things so seriously. anyone else go through the same thing?
