Its about avoiding conflict and having full confidence in yourself and you ability that if you cannot talk yourself out of trouble
you can handle the situation to a successful conclusion..
I done cage fighting for a bit there studying BJJ, Judo, Thai.
Personally the TKD stuff doesn't do it for me at all. I prefer stuff the resembles real life fighting situations.
