First is to get them to appreciate and work at their short game. Use their imagination and experiment with different short game shots while practicing and on course when playing alone.
Second play holes from the practice tee. Go through their routine and play holes on their course on the practice tee—hit a tee shot, then an iron second and a chip/pitch if they miss the green, then imagine and play another hole.
Third is to just go play. On each shot make a practice swing feeling the shot they want to hit, then go through their routine, focus on the target and not mechanics and hit the shot.
