#4 can also be wrong but in someways,if you do not test your skills on the mat with other then people the people in your dojo how would you know if you have any skill at all? tournaments are not about winning and losing its also about helping the dojo and learing. If your master cares more about money then you Learning in the art then thats the wrong dojo to be in. #5 playing games with your little students will not get them no were.its ok to have a few jokes here and there but if there not serious in training the whats the point of teaching then self defense.you have to show your students that fun&games are after class but training is serious during class. #11 Your belt sybolizes you in your training. The belt colors are symbolic philosophically and spiritually in the Karate System of Contemporary-Traditional Martial Arts. It will not only benefit the student to learn the philosophy behind each belt, but to share it with others. Martial arts were created to protect the religious and philosophical beliefs of the people who practiced them. Different martial arts have been so changed in the United States for sports competition that much of their significance has been lost. It is up to the serious student to carry on the traditions that give the Karate its birth and heritage.its not a matter of tripping or slipping on it, its a matter of honor and respect for your art of Karate.
