One very effective drill in perfecting your swing is to let the ball 'get in
your way' as you swing toward the target. In other words, you let the ball
get hit because it was sitting there in the way of your swing, not because
you were swinging at it.
This drill shows why many people have better practice swings than actual
swings where a ball is involved. Without a ball it is easier to swing through,
yet this is the very motion that is needed when perfecting your swing.
A key in helping correct this tendency is to learn how to separate the optical
eye from the 'mind's eye'. The optical eye sees where the ball is sitting,
while the mind's eye sees the ball sailing toward its target. Remember, the
ball is not the target, so the key is to avoid being tricked by your optical eye.
Instead, let your mind's eye swing to your target, which is the fairway or the green.
This is not to say that you don't look at the ball at all, but rather to stress that there
is a great difference between looking at the ball and
concentrating on it.
