I've been studying the martial arts for the past 12+ years.  For the past 4, I've been studying Kenpo Karate.  I really enjoy it and have my Brown II in it.  Lately though (past 5-6 months), my motivation hasn't been there.  I don't know what it's been.  I just don't feel like going.  I can't really explain it.  I'm kind of in a rut.  Has anyone else out there felt this way?  If so, what did you do break out of your rut?    Any advice would be great.  Thanks...
