Frequently on the lesson tee, I am asked "How high should I tee my driver?" It depends on how deep the face is on your driver. As a general rule of thumb, the equator of the golf ball should be at the top of the face of the driver.
Listen, don't look!! Most golfers miss short putts because they watch the ball roll. If you watch the ball roll, you will tend to open or close the clubface. As difficult as it may seem sometimes, listen for the ball to hit the bottom of the cup before you look up.
Remember: On short putts, if you look up too soon, you'll see the ball missing the hole.
