If you are practicing and start hitting bad shots then step away from the ball and work on re-establishing solid contact with a few bump shots in order to get the feel for center clubface hits
By moving the ball around in your stance and using different clubs you can create many different shots to use around the green
Narrow down your focus on short putts by putting to a tee and trying to hit it dead on, this makes your short putts much more exact and gives you tremendous confidence when you are on the course putting to what looks like an enormous hole
