If you're pushing the ball off the tee--or even worse, hitting shots that start right and then slice--you're probably getting pretty panicky with the driver. In many cases, you can fix a bout with "the rights" by playing the ball two to three inches farther forward than normal. Those way-right shots come from swinging down on a path that goes from well inside the target line to outside the target line after impact--too much in to out. If the ball goes straight right, your clubface is square to that path but open to your target. If the ball also curves right, the face is open to the path. Moving the ball forward helps square the face to the target at impact and will get you swinging on the correct path through the shot: from the inside, out to the ball, then back to the inside.
