For the choke, there are no 'tough guys'

Jiu Jitsu is a mousetrap. The trap does not chase the mouse. But when the mouse grabs the cheese, the trap plays its role.

Always assume that your opponent is going to be bigger, stronger and faster than you; so that you learn to rely on technique, timing and leverage rather than brute strength

For the choke, there are no 'tough guys'

For the choke, there are no "tough guys". With an arm lock he can be tough and resist the pain. With the choke he just passes out, goes to sleep.

Jiu-Jitsu is like a philosophy. It helps me learn how to face life.

You should never have a power, in any area, with the purpose of harming someone.
