Joe Rogan said it best.
"In life, we can all distort our perception of things in order to make ourselves more comfortable, in order to make ourselves accept where we are. And there’s a lot of people out there that are running around in life full of shit. You can’t be full of shit when you do jiu jitsu. When you do jiu jitsu, its impossible to be full of shit because reality comes at you in the purest form possible: A life or death struggle, using your determination, your focus, your techniques, your mind, and your training, over and over and over again."
