This advice is far easier to give than to get you to actually do it.  When you hit an errant shot, don’t say “what did I do wrong?”  Instead, ask what you “didn’t do right.”  Thinking about doing it “wrong,” can mislead and confuse you.  Keep your focus on executing shots the right way instead of the wrong way.

Do not think while making your stroke, do your thinking prior to the stroke.  Because you cannot think about any more than one detail at one time, it is futile to think at all during your swing.  Keep your mind clear and just make solid contact.
