Giving credit where credit is due.
I’ve been training and teaching for a long time now, since the 80’s to the present. The bulk of that being in the Filipino Martial arts followed closely by the Thai Martial arts. One thing I always try to do is be honest about what I’m teaching and where it came from. Unless you are just making stuff up, you are standing on the shoulders of those who came before you.
No matter whether I am teaching a direct concept, or showing comparisons between systems I’ve trained, I will always acknowledge the instructor/system I directly learned it from. I will also be honest in where I diverge, disagree, and where I’ve changed things due to my experiences and influences across systems.
I don’t make crap up, and I don’t steal things from others systems I haven’t directly trained in and try to call it my own. My focus in training and application has changed overtime as I’ve been exposed to different instructors and systems, but the main tenant of continuous improvement in learning and application is alway key.
Acknowledge where it came from, and strive to carry it forward and produce students who are better than you are. If that’s not your focus, then you are not an instructor, you are a practitioner. Nothing wrong with that, just be honest about it.
