I feel you man. Work for me has been hell. You just have to get re-organized and set up a goal again. Think of something you would want to specifically improve and take the weekend to make a game plan. That is how I get out of ruts... That and the people at my MMA school tell me to put my man pants on and stop stalling.....
SSOOoo...
PUT YOUR MAN PANTS ON AND START SMASHING METAL!
