We all go through burn out, and sometimes a little time off is the answer. I quit training Kung Fu for 3 years after my Sifu moved away. I picked up again when his Sifu began teaching again and attained my black sash under him. Sometime after I took two years off and trained exclusively in boxing because I always wanted to. When I returned to Kung Fu I was that much better.
Somtimes we may veer off the path, but as long as we continue the journey all is well.
"The hero and the coward both feel the same thing, but the hero projects his fear onto his opponent while the coward runs. 'Fear'. It's the same thing, but it's what you do with it that matters". -Cus D'Amato
