Something else that's probably the most simple trick yet and may work for you is teeing your ball, then turning the lettering on the ball so the words are aiming down your target line. Similar to what a lot of golfers do when lining up a putt. Take that word as the center of you ball and when you swing, aim your clubhead just inside the lettering. That makes it so you are focusing on hitting not the whole ball but just a small point about a quarter of an inch away from the back center of the ball towards you. Inside out. Try it, it might be a simple fix.

Or you could try what someone posted on another thread awhile back. Take the club you hate hitting the most and tee your ball up so the tip of the clubhead is about 1 inch from the side of your garage then swing away. LOL. That could do some damage to the side of your garage but it sure would cure an outside in swing.
