nothing is going on in my mind.maybe watch the speed of the other players if they are on my line.i don't start thinking until it is my turn to play.
after i put my ball down all systems go.i read the green from both sides of the hole,then i get behind the ball to start my routine.which by the way is really simple,,,,,3-f-5 and go...that's it,where you expecting more,golf is hard enough so don't sweat the small stuff.just remember KISS,this was payne stewarts favorite saying.he won a few majors keep it simple stupid(kiss)
the putting drill i use for speed is,look at the hole and hit a few putts.then i hit a few more and close my eyes at impact and try to guess where the ball finished.this is a great drill to learn feel.i do not spot putt nor think of anyhting other than where i want the ball to go in the hole.by this i think of the hole as a clock.on a putt that breaks rt to lt a fooot lets say.i would see the ball going in at 3 oclock.thats how simple i make it.as far as the stroke is concerned i work on letting my right arm straighten down and out,just like my driver swing.i zero out #3 power accm. so now i have angled hinge action,tracing a straight line.thats it pretty simple for me anyway.
