How can I improve putting a golf ball?

bought a new putter today..a two ball.

Have always been a good putt. I tend to think all golf swings are the same including putter, that is you have to keep you head still and eye fix at the ball. I’ve played snooker before and I think it helps.

With putt, first you read the line, the slope and the grass, then align your ball path, give it a point where you want your ball to stop (e.g. if it’s uphill you want the ball to stop after the hole, and down before the hole, break left right of the hole, and right left of the hole). Then, you pretty must know where your target is (like you would any golf shot), then execute it by eye fix on the ball, and have a good swing. Once you made up your mind on the target line, nothing else would help except positive thinking, just hit the shot as planned. Picture every putts go into the hole, that’s the only way it should be done, into the hole.
