I was reflecting today on my (arguably variable) abilities as a teacher of Tai Chi – wondering how to better “get it across” to my classes of likewise variable ability, age and education – and was struck by the observation that actually the biggest problem I have is with students who think they know it all. They may exhibit this immediately or it may take a year or two.
I recall advice from one of my teachers in Hong Kong to “be humble” and finding that being humble simply means to have a realistic understanding of ones ability. Such otherwise closed mindedness is a sure barrier to learning on a personal level but worse it can poison a whole class if only by taking up excessive resources and creating distraction – if you are bored or think that the teacher doesn’t know what they are doing then please leave and seek another teacher – or preferably keep quiet, then stay and seek to understand by redoubling your own efforts, rather than blaming someone else.
