I am glad that you were able to live this facet of your life in this way and to receive with open arms the teachings that the Asian martial arts gave you. How wonderful for you! The kind of discipline of body and mind always finds my admiration (like accepting broken ribs!), and if there is one thing I miss, it is probably the level of determination and continuity of never having done a sport myself that would have offered this to me. My ambition was not strong in this respect.
I can understand to some extent that constant practice and frustration take place in, say, painting or origami, where you have to travel many miles to create a good piece of work, and I can imagine it is similar to experiencing a good fight after you have trained so long and hard. The special satisfaction of passing on some of that to apprentices or students, on the other hand, I understand very well. I loved taking the young people aside and getting them interested in the discipline in which I myself was professionally trained.
As far as dancing is concerned, I have made an attempt here to tell what it means to me. I don't know if I will return to the subject in the near future.
