Another point, if I may. Actual qualifications. Years ago I had a job as a technical trainer. When I had to teach a subject that I was only a paper expert, haven never done what I was teaching, I felt like a fraud. https://youtu.be/LAFuWczEv1s
Martial arts teachers who have never been in an actual adult fight with someone with bad intentions teaching self defense. A 6'3' 230 lb man teaching self defense to non-athletics women. What the hell do they know about it?
Just my opinion but unqualified frauds could be added to your story though your story is complete without that. There are too many of them. A thousand dollar weekend certification does not an expert make.
