Re: Talking too much
There is definately a time for talking and a time for training. Don't forget your sensei is a human being, and, if like me, has only had a few years experience instructing, they may not be aware of the problem. Maybe you should mention/infer that you don't get enough time to practise those things he/she talks about? The worst that can happen is that his ego gets in the way and you have to go to a new club. However you may also improve the club and teaching tremendously. (good martial artists are not always good teachers, and the teacher-student relationship is a 2-way thing).
