I can put it within 15 feet of the hole.
Then learn how to put from 15 feet.
As far as putting is concerned, you need to learn how to not 3-putt. Practice putting from 6 feet and under. You want to be able to make 90% of those putts. 95%+from 3 feet. Then, when chipping or putting from long distance you draw a bullseye around the hole. A 6 foot ring, and a 3 foot ring... Practice chipping or lag putting until you can consistently get the ball inside your rings. 90% of the time.
This is something you need to work on every spring because you lose it without constant practice.
