Preparing for every shot is one of the most common differences between Tour Players and amateurs, not thinking through every aspect of your shot prior to hitting it will lead to more mistakes and the common occurrence that the second shot you hit is always better
When you set up to putt pay attention to what your head and eyes do when they check the target, players who line their putts up right or left will have their head and eyes move towards their left shoulder or up to the sky rather than directly down the target line
Make more of your mid-range putts by practicing hitting the putts past the hole with this simple drill, giving you a better chance of making putts because they will all reach the hole
