I'm selling evolution. You grow or you die.
The only guys that make it through are the guys that make it through are the guys that have a complete control of their ego where they tap out in the beginning, all the time, you're always losing in the beginning... Your ego can get bruised if you don't have control of it. So what ends up happens is Jiu Jitsu is the ultimate douchebag filter.
