Close your eyes and imagine a 10 foot putt. In your mind’s eye, feel your stroke as you prepare to make the putt. Then, set up over the ball and make your stroke. See the ball roll towards the hole, hit the back wall of the cup and hear it fall into the hole.
Repeat for putts of different lengths and breaks.
When summer comes, you will be able to do this for real.

you must remove all negative thought from your putting process. Visualize to within 3′ for longer breaking putts and back of the hole from within 10′.
I’m a putting legend — in my own mind. I have a portable putting carpet in living room and I often visualize sweet putts. It does not hurt to make believe.
“the Body has a Mind of its Own” 5 days of imagery is equal to 3 days of physical poractice good stuff for the whole game.Great tip Frank
