I found the DMP site a couple of weeks ago and I'm so glad I did. I'm already learning a lot.
I went to art school in the sixties, when teaching was uncool, so I didn't receive any. I remember asking an instructor if a sable brush would be worth the investment. The answer, beginning with much used profanity was: Man, don't ask me that, go paint with your tongue! I'm trying to teach myself now, and I think this method is going to be a great help.
