Have you ever wanted to do something, but were afraid of being shown up or making a mistake? Let me share my experience with this.
My student had been selected by the teacher for practical applications (self defense) demonstrations, and had been thrown about quite roughly. The other students found this most amusing, and treated it like entertainment. Whenever the teacher asked for a volunteer, my student stepped up for more. The rest of the class found this hilarious.
I was very happy with this outcome. I used to do the same thing with Master Liming Yue. Whenever he wanted to demonstrate techniques, I was always the first to volunteer. Sometimes, the other students would laugh. But knew I was getting better.
Martial Arts are about making mistakes. For only by making mistakes, can we eliminate errors and get better and better. As we get better, the opportunity to make these mistakes (lessons) gets smaller and smaller. It is those who can safely put themselves into situations where they can learn from their mistakes who will achieve the greatest.
As for the student - he went on to become British Open Kung Fu Champion later that year.
