In battle, do not think that you have to win. Think rather that you do not have to lose.
Gichin FunakoshiYou must be deadly serious in training. When I say that, I do not mean that you should be reasonably diligent or moderately in earnest. I mean that your opponent must always be present in your mind, whether you sit or stand or walk or raise your arms.
Gichin FunakoshiWhen you leave your home, think that you have numerous opponents waiting for you (it is your behavior that invites trouble from them).
Gichin FunakoshiYou may train for a long time, but if you merely move your hands and feet and jump up and down like a puppet, learning karate is not very different from learning a dance. You will never have reached the heart of the matter; you will have failed to grasp the quintessence of karate-do.
