1. Light grip pressure
2. The length of your backstroke should match the length of your through stroke
3. Consistency in the pace of the stroke. Meaning don't go back fast and decel through, and don't go back slow and then speed through the stroke.
4. Do the above and let the ball get in the way as opposed to striking the ball.
5. Aim small, miss small. Don't listen to people who say to hit it to a 3 foot circle cause if you miss it by 3 feet now you've got 6 feet.
6. Be more athletic. Think about a shooter. He just shoots, he doesn't go through a checklist before shooting. Do all your thinking prior to getting into your stance. Once over the ball, shoot.
7. When trying to read the green don't just look at your line. Look at the entire green. This will let you know if, for example, everything is funneling to the front left of the green.
8. Don't read greens with just your eyes. Use your feet too.
9. If you're over a 15 footer and the line is a ball out to the left, don't aim there. Instead find a spot, imperfection or something on the green about 6 inches in front of the ball and use that mark as your spot. Either over the spot or just left or just right. This also works on the tee shots and approach shots.
10. Practice!
