Consider fully, act decisively.

In Randori we teach the pupil to act on the fundamental principles of Judo, no matter how physically inferior his opponent may seem to him, and even if by sheer strength he can easily overcome him; because if he acts contrary to principle his opponent will never be convinced of defeat, no matter what brute strength he may have used.

Nothing under the sun is greater than education. By educating one person and sending him into the society of his generation, we make a contribution extending a hundred generations to come.

Judo helps us to understand that worry is a waste of energy.

The teaching of one virtuous person can influence many; that which has been learned well by one generation can be passed on to a hundred.

In an argument, you may silence your opponent by pressing an advantage of strength or of wealth, or of education. But you do not really convince him. Though he is no longer saying anything, in his heart he still keeps to his opinion, the only way to make him change that opinion is to speak quietly and reasonably. When he understands that you are not trying to defeat him, but only to find the truth, he will listen to you and perhaps accept what you tell him.

Apply just the right amount of force — never too much, never too little.
