1st and foremost for me is confidence in my putting stroke period. 2nd I got the confidence by trying different methods recomended by instructors, helped some but deep down I felt it wasnt my stroke, so I stated over by simply making sure of a few things. First I had to make sure I was consistantly rolling it straight, took awhile but straight is straight, and as the saying goes all putts are straight, next I found out what was the lenght of my putting stroke I could do consistantly without causing the ball to go not straight and how long would the ball roll, this part is crucial cause on slow greens it will be less and on fast greens it will longer. Good to practice on the practice greens before a round. Once I know how long the ball will roll on the practice green with my puttting stroke I have much more confidence in making adjustment on the course for longer or shorter putts.
