At the end of JRE 460, Kron Gracie talks about how jiu-jitsu reveals what a person is really like.

I judge somebody on how they train. I don’t judge somebody on how they talk to me. Sometimes I’ll get people who are super nice and super respectful in person, and they’re just a perfect person, right. And then when they train, there’s this malice from them. It’s weird, and you’re like, “Whoa, that malice is for real.”

They put on this act, but when you’re training, there’s no way you can hide your personality.

I don’t judge too much on what you say and how you are. Of course, I feel it. But, when I train with you, I’ll make my final decision.
