Golf gurus have been preaching for years that the real secret of golf is mastering the mental game. But it's not enough to merely think through a shot in the moment before you tap the ball. As famed golf teacher Fred Shoemaker explains in his book "Extraordinary Putting: Transforming the Whole Game," you also have to pay attention at the moment that you're putting. Intention, he explains, has to be followed up with commitment to translate what you have visualized into action. He writes: "If we don't clearly choose a place to put our attention, the default place that our mind typically provides is 'How do I look?' or 'Did I perform well?'" And that's not going to help you put the ball in the cup [source: Shoemaker].
