A while back I wrote this on my wall in facebook, "Don't let what you know get in the way of what you could learn." I was thinking how at times our own knowledge gets in the way of learning something new or different. As we spend years/decades training and learning, we sometimes become more rigid in what we believe is the "correct way", or our way, of doing things. So when an idea comes along that may contradict what we already know, we resist it instead of looking at it objectively and weighing all it's pros and cons before making our decision on the idea. Which makes me think of something else I often say, "Do you want to be right or do you want to get better?" Often when something comes along that contradicts what we may already know, we feel threatened by it. As if it may invalidate everything we have learned and done before. So we spend time arguing against the idea to defend our view of our martial arts world or we dismiss it, based on what we already know. Of course presentation matters. Presenting an idea on it's own merits can go a long way to how people will react. However, if you start by trying to invalidate another idea, or saying mine is better than yours, it will degenerate into a pissing contest rather quickly.
