If there is effort, there is always accomplishment. - Kanō Jigorō

Jigoro Kano's Five Principles of Judo:
1. Carefully observe oneself and one's situation, carefully observe others, and carefully observe one's environment,
2. Seize the initiative in whatever you undertake,
3. Consider fully, act decisively,
4. Know when to stop,
5. Keep to the middle.

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.

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 part in public entertainment for personal gain. Teachers certainly receive remuneration for their services, but that is in no way degrading. The professional is held in high regard like the officers of a religious organization or a professor in the educational world. Judo itself is held by us all in a position at the high altar. To reconcile this point of view with the Western idea is difficult. Success or a satisfactory result of joining the Olympic Games would much depend on the degree of understanding of Judo by the other participating countries.
