If your tee shots are going sky-high (and you aren't intending them to do so), there are a couple of things you can try.

1) Your hands are probably too far ahead of the club face when the face is hitting the ball. Try using a shallower swing and concentrate on your hand location.

2) Keep your head behind the ball during your swing. This will help bring your hands back.

3) Look at your tee after the shot. If it is buried into the ground, the path of your swing is too steep. Work on your swing path.
