Most of us don’t consider how our self-talk directly affects our performance and play. Unlike the immediate feedback we get from the body and the swing, we fail to see a real-time correlation between the quality of our shots and the content of our mouths.  From an energy standpoint, however, there is no way we can berate ourselves on any level and hope to optimize performance and success. Just as there is no such thing as an ordinary thought, there is no such thing as an ordinary word. In a very real sense, the pen remains far mightier than the sword.
