You have plenty of time to think before you hit it, and plenty of time to think while you walk or ride to your next shot, where you think some more before hitting it again, etc. You can think yourself silly, and then you'll usually play that way. If you know how to think on a golf course, however, your chances of playing up to your potential are greatly improved. The victory was Inkster's first of 2001 and the 26th of her career. Over-thinking, or too much analysis, is counterproductive.
Most amateurs are over-analytical.
They try too hard, they care too much and they expect too much. In 'Going Low,' I talk about letting go of expectations of what is and isn't possible. Their minds were free of mechanical thoughts. Top professionals are able to re-create that type of thinking often, and although it doesn't mean they'll automatically shoot 61s and 62s, it explains why they are able to play to their potential more consistently than amateurs. Obviously, the best players in the world don't do that.
