I don't teach kids. We play with knives. Hard to take on the responsibility of teaching someone else's kid how to play with blades. That is their elder's job.

I charge about 1/3 to 1/2 the going rate of other schools in my area, with a payment waiver for people who are broke but love the training. But if you no pay, and you no practice, I no have you around

It seems to be working pretty well. I'm still around when other guys locally have gone under. If I were going for a truly commercial school though I'd start a kali/MMA school. The "Fu" is different though. Who wants it these days? Better to have 10 good ones than 50 indifferent ones that make you grit your teeth every time you teach.
