When you are just starting to play golf, you are frequently warned to
not hit the ball too hard. Energy that is focused will make the ball
go much further than a hard swing that does not make contact with the
ball at the club's center. When you are well balanced, you are more
free to hit the ball correctly.
I have created a blog that gives more details about this. You can
