When we putt we are looking down at the ball and lose perspective of the actual distance of the putt, so take a mental snapshot of your putt before you look down at the ball to increase your distance control
Do not put pressure on yourself as you approach the final few holes and have a chance to break a personal milestone, take each hole on the course as a separate game and try to win that hole, then move on to the next one disregarding your previous scores
Select clubs for your bag based on your game, if you are a beginner stay away from the high lofted wedges and stick to more hybrids while the advanced player should have interchangeable clubs that he selects based on the course and conditions he is playing
