Aim at nothing, and you will hit it every time.
Think about some other sports – fishing, javelin, rugby, football(soccer), snooker, tennis, cricket, darts, etc. Aim is critical to all sports. I remember seeing a film about Babe Ruth, the baseball star, and seeing him eye up where he wanted the ball to go. You see, the ball is not the target.
In around 1982, whilst working at Copthorne Golf Club in Sussex, England, Bob Lee and I went out to play. We did something very unusual, we call the shots before we hit them. We described in detail how we were going to hit each shot, and both play remarkably well. Bob described his tee shot on the par 3 17th, that he was going to hit his 8 iron just left of the hole with a little fade, and let the wind move it a little more and it would go in - and that is exactly what he did!
Now obviously there is a lot of psychology involved which we will get into at some point. What I am saying is this: have a specific target in mind, just getting the ball down there will not do. Even off the tee, aim for a discolouration in the grass, or a specific point, or an object in the line of flight.
It is certainly true in every other sport that if you aim at nothing, you will hit it every time, and it is just as true in golf.
