The lack of discipline in modern TKD is the end result of young inexperienced instructors, a lack of understanding history, and our sparring culture. Most teachers / masters find it extremely difficult to build a champion fighter and teach the discipline needed to be a complete martial artist. TKD today has become fight centric, it's being treated as a sport instead of a art. TKD has fallen into the mma trap, we want to compete so much that we've forgottent the principles that make us the most popular art in the world.
