Since we know that approximately 75% of the shots you will take will be from within 100 yds, PRACTICE. PRACTICE, PRACTICE the short game. Just try to make it FUN and challenging. Create games for yourself with different short game shots and try to keep score to track your improvement.
Like all good players do, try to make every shot inside of 30 yards. Maybe try one shot with a wedge, the next from the same place with a 9 iron or other club. Try opening and closing the face on some shots, until you can get up and down from many different places.
Then try other ways to have fun with practice, play your buddies for braggingh rights, closest to the pin from anywhere around the green. And remember this, “amateurs teach amateurs to be amateurs”, so take some clinics and group lessons to learn a lot and then go practice what you have learned from the professionals.
Good luck and have FUN !!!!!!!!
