Seriously, i think we all go through this. I'm sure there are a few people, myself included, that have pondered leaving gung fu or stopping your training for a while. You just need to change gears for a minute, maybe pick up something else non martial to do or even learn or focus on a different aspect of your training. sometimes going back to basics helps as well.

If you've been doing gung fu for a long time, you can never just walk away from it. So, give it some time, watch some gung fu movies, look at others train, or whatever. but my sifu would always tell me that would be the best time to train..when you don't really feel up to it. OR, what about a partner? do you have someone to help you train?
