I'm not complaining or whining, all those same things that are the pains of learning a martial art, are also the joys of learning a martial art. After a little while, the newness of learning a martial art wears off, and all you're left with is the more difficult parts. That's where you have to find your joys. Find joy in learning a new culture and language. Find joy in that awkward, uncomfortable position slowly feeling more natural. Find joy in the ability to push past the learning curve and find pleasure in incremental learning of new skills. All of those are the real joys of learning a new martial art.
