How long have you done your style of martial arts and why have you stuck with it. ps for instructors only?

I wholeheartedly agree with possum. I have seem the results of too much mixed-up training. As possum stated, do look into what ever interests you, but maintain your training in your chosen core martial art. I had a student once who had more green belts (6 or 7 styles) than I could believe. He had been training karate for almost 30 years (not much less than me at the time), but his obi was green, as were his other belts. He was a good green belt, but his skills were indicative of his belt! After so long it seems he should have progressed farther. Had he stuck to any one of then until shodan or nidan his other training would have been more meaningful. I'd suggest you endeavour to reach BB level, and continue the study of your chosen art. You can then learn much more from others of other styles as well, without abandoning what you are really all about. Best wishes.
