Brazilian Jiu Jitsu is hard, both mentally and physically.
Anyone who has ever stepped on a mat knows this. You get your ass kicked repeatedly with extreme prejudice, and your coordination sucks. Mostly because you simply don’t know what do, and how to process the conceptual framework of bjj. My observation has been that most people struggle through the end of their white belts until they begin to realize that bjj is a system of movements, and that each submission, sweep, pass, etc. are all based on only a handful of core principles. Once those principles are grasped, learning becomes much more facile. That’s why a brown/black belt can pick up new moves faster that beginners. Simply because they realize that what they are learning are simply variations on a theme.
To use another example, it’s like learning how to have sex. Sure, I was really bad at it when I started, but after a few years, by the time I was nine I really had the swing of things, and by 12 I had pretty much had the entire Kama Sutra at my disposal and command. All by discovering and applying the rules of eroticism. It’s just a matter of practice and mindset.
Now I don’t know if I’m a world class lover/ok bjj player because I understand these concepts, or that I understand these concepts because I’m a world class lover/ok bjj fighter. I recommend you don’t think about that too hard because it’s a chicken/egg question and the metaphor doesn’t extend that far.
Hey man, I’m just throwing ideas out there. If you want sound logic go read Socrates.
