I play a lot of golf with mid handicappers and high handicappers and one thing I want to do is shake a playa up and tell him STOP! THINK for 10 Mississippis! You have all the ability you need inside your bones and brain! Stop for a moment.
This is one of the PLAYING PURPOSE range of ballmarkers. I want you to keep this in your pocket, on your hat clip, whatever you do, and use it on the greens. Every time you look at it remember it.
When you're looking at your shot, just give yourself 10 seconds of 'me' time and think and strategize without auto-pulling clubs, shooting at the flags willy-nilly and bombing driver on every hole.
