You don’t have to knock the dimples off the ball on every tee shot in order to lower your score. As a beginner the putting green is the perfect place to rapidly lower your score. So many shots are added to a beginner golfers scorecard due to missed putts which in all honesty are almost criminal acts preventing them from lowering their scores.
Make a note of how many putts you make in a round of golf. Are you 3 putting? How many times? If you add up all your three putts e.g. In a round you may 3 putt on 5 holes. If you scored 104 for the round you can see that if you had two putted on those holes that you would have broken 100. The easiest way to practice is to putt balls a certain distance consistently.
I like to putt the distance of my golf umbrella. That distance can be a tester but if you keep putting that distance either at home every night on the carpet or even the practice green at your local golf club. Putting is a skill like being a guitarist. How good do you want to be? The more effort you put in the more you will be rewarded.
