I came here to say this. A few years ago I picked up JJ as a side hobby, and it quickly became my main hobby. I still weight lift and do cardio, but it's all in service JJ now.

Putting oneself in stressful situations over and over leads to more calmness when under stress in general. Then there is the ego check where where one is forced to be a beginner again over and over. There's also no way to lie to yourself when a 100# girl chokes you out.
