Relax Damn It! Let go, let the motion be, dont try to do the technique, let it flow through you. I have found myself saying these words over and over again in the dojo. And yet the words seldom sink in deep enough to cause real change.
Modern life, especially with all of the technology we have is driven by stress. Unless you actively get on a program to de-stress as a martial artist, you are in serious trouble. Why should you care about it?
