Visualizing the flagstick as a tall object can help you make more shots up to the hole
Do not assume that every par four and five is a driver, you need to tee off with the club that is going to leave your next shot in your favorite scoring position, hitting your tee shot too long often hurts your scores
The area from 150 yards and in is called the scoring zone because by far the majority of golf shots come from inside that zone, so having good irons and working on this part of your game will have the greatest effect on your scores
