Another point is the meaning of professionalism. With Judo, we have no professionals in the same sense as other sports. No one is allowed to take par… - Kanō Jigorō

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.

Judo teaches us to look for the best possible course of action, whatever the individual circumstances, and helps us to understand that worry is a waste of energy. Paradoxically, the man who has failed and one who is at the peak of success are in exactly the same position. Each must decide what he will do next, choose the course that will lead him to the future. The teachings of judo give each the same potential for success, in the former instance guiding a man out of lethargy and disappointment to a state of vigorous activity.

In randori we learn to employ the principle of maximum efficiency even when we could easily overpower an opponent. Indeed, it is much more impressive to beat an opponent with proper technique than with brute force. This lesson is equally applicable in daily life: the student realized persuasion backed up by sound logic is ultimately more effective than coercion.
