I never get mad at students & I think I'm doin a pretty good job with the 20 students I've got. Including developing relationships and knowing what direction to take with them.
I've been at this for 15 years and not too long ago was running my own music store with 8 teachers working for me so I do know what I'm doing.
I'm just trying to point out the futility sometimes of giving a student a half-hour lesson for $25 a week when there are better alternatives available.
For instance, I'm sitting here for 3 hours on a lesson sometimes and recording a half dozen MP3's and with some students I'm doing that ten times a month. I'm also writing out & describing techniques in detail that you can re-read at your own leisure, plus giving tons of studio and music business advice. I think it's a way better deal to spend $50 a month for practically unlimited lessons and having me available every day by email, rather than paying me $100 a month for just four, 1/2 hour lessons.
