Judoka is always ready to help a person who is weaker than him. The strength of spirit and power of a Judo fighter can defeat any villain. Even stand of judoka causes the thieves to flee, showing his weakness. "Physical self-improvement is not enough in itself, because, no matter how strong a person becomes involved in judo, no matter what skill he has not achieved, if he is not useful to society, then his life will be in vain." Jigoro Kano
