Yes, I just quoted myself in my own title. I'm sure that says something about my mental state, or something.
Even when I first wrote that, I knew I wanted to pull it out for a quick examination.
Because really, sometimes I write about practices or ideas that I think are stupid, and I can hear students or training partners saying "but, Jake, didn't you do that?"
So, yes, yes I did. I have tried a lot of bad ideas over the years, and made a lot of mistakes. I have at least one student who I frequently beg to learn from my errors.
Just because I did something doesn't mean it was a good idea.
