The purpose of training is to tighten up the slack, toughen the body, and polish the spirit.
There are no limits. There are plateaus, but you must not stay there, you must go beyond them. If it kills you, it kills you.
The ultimate aim of karate lies not in victory nor defeat, but in the perfection of the character of its participants.

A martial artist who does not train daily will not reach the heights of their potential.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.
To be a great champion you must believe you are the best. If you're not, pretend you are.
When the opponent expands, I contract. When he contracts, I expand. And when there is an opportunity, I do not hit. It hits all by itself.
