Is it just me or does anyone else happen to do this also. Your instructor tells you time and time again this is important because of ... So you put that in the back of your mind for safe keeping and then years later LIGHT BULB ! That's why this is so important. I have been training for 17 yrs now and the things that I knew were important some times just hit me from a different perspective and it can change everything for you. Recently I had a revelation and it has simplified my taijutsu greatly. I suppose knowing something is important is good but without years of hard training, some sweat, and a little blood now and again you can never get to the point of the reason why it is so important. The difficult thing is what can be a game changer for me you may have known for years and your break through some one else new from the very start of their training. Everyone has their own training experiences because everyone moves differently but sometimes I think wow if I had only could have understood this much when I started but I suppose that is the point in training. You have to figure these things out for yourself.
