Try using a few of these steps to create your own personalized pre-shot routine which will help clear your mind while creating the perfect alignment, ball position and clubface needed for consistency
Keep your feet quite throughout the swing, eliminating sway and bad balance, just let the body take the feet where they need to go, left foot slightly inward on the backswing, right foot on its toe on at the finish with all your weight equally supported on a flat left foot
Use the Aim, Look and Go system to take care of your putting set up prior to the putt so you can clear your head of all thoughts and putt relaxed
