Dojo Kun #3 : Endeavor (Effort)
動力の精神を養うこと (Dohryoku no seishin wo yashinau koto)
To endeavor means complete dedication and commitment necessary to achieve mastery of the art. In no case is mastery possible without strenuous effort and sacrifice on the part of the practitioner. The endeavor must be of a sincere nature and not just superficial. Serious effort on the part of the student will be recognized by the sensei who will in turn spend more time with him or her.
