Re: How to Leave a Dojo?
Don't .... I would accept students at what ever they could afford according to their circumstances. Most of the dojo fees were covered by me anyway, so if a student was genuinely hard up, it was better to come and practice rather than leave. Good students are hard to come by and it was always those who couldn't afford it were generally the best.... Aikido has kept me relatively poor many a time and I have sacrificed many a holiday to keep the club going when I had it.
Be upfront with your sensei, I'm sure they will be upfront with you or at least I would have thought so....
