When Do You Know Everything About Jujitsu?

Uncle Jake: You never know everything about jujitsu but that shouldn't make you sad. I've been training jujitsu for 25 years and I still don't know everything at all about it. Just like jujitsu you can always learn more and that's called being humble. Being humble is part of the warrior kid code, so go out there train hard study hard work hard get after it and be a warrior kid.
