You have decided that you want to lower your handicap.
At this point you are getting serious about your game and you want to take it to the next level.
Congratulations you are now ready to take your game to the next level.
Making that decision is half the battle.
Once you know what you want to achieve then it is easier to achieve it.
As you know there is the law of cause and effect.
Something is causing you to score higher.
What you need to do is monitor your game as you are playing it on the golf course.
You need to take detailed notes so you know what the details of your actual game are.
For example are you missing the fairways? Are you hitting the greens on your approach shots? How many putts does it take for you to put the ball in the hole once you are on the green? What length is your average drive? Are you hooking or slicing the ball either with your driver or irons.
The point is you need this information and I think you are smart enough to know why.
You need it on order to know what to improve.
I could write a whole article on how to swing a club and so on.
All that information is passive unless you know actively and specifically what is actually happening in your game.
For me to talk about improving your game is one thing, but it is quite another for you to understand exactly what in your game needs improvement.
Once you understand that then you can consistently improve and lower your handicap for good.
