I do primarily when I putt

I try to visualize every shot I make, from tee to green. I see the ball's flight and distance, and try to see the line of my putt tracking to the hole. It has helped my concentration and helped my game in general.

I think everyone visualises to some degree, whether they think so or not. I'd say it's virtually impossible to play golf without thinking about where you want the ball to go.

I try to with putts, but get lazy/rushed some times. I need to keep at it because I'm a much better putter when I do. I like to get down and follow the line that I see the ball taking with my eyes.

Or don't go and that is where you can have problems. You see water or a sand trap and you immediately fear it and see your ball going there. So what happens? Yep, the ball went right where you visualized.

Yeah, good point. Negative reinforcement somehow works better than the positive kind. Don't slice don't slice don't sli....argh darnit.

Been there, done that many times but now I try to have the last image in my head to be something good.

I visualize every shot. Trajectory, what it'll feel like, how it'll behave when and where it lands, how it'll move after landing, ball travelling on the line, entering the hole etc. If I can't visualize it then I usually hit a poor shot.

Your body doesn't hear don't slice, don't slice. All you hear is slice, slice, slice. You have to think straight, straight, straight. How often do we see this on putts as well? Don't leave it short....and it ends up short. Think long, long, long.

My coach gave me this tip while putting and it has changed my putting game completely. Pick your spot to putt and it should never be the "hole". Pick a blade of grass on the edge of the cup and swing for that if it is a straight putt. The last thing you look at before swinging the club should be your spot, NEVER the hole. Once you look back at the hole, your body changes its entire alignment.

I visualize all my shot's. I walk mostly and feel that walking helps set my eye up for the slope of the course and how I want the ball to travel to it's intended target. Obstacles are realized and alternate shot's are chosen if needed.
As far as Putting absolutely I have to visualize the Putt. On super long putt's rather than only thinking of putting the ball in the hole I see a bushel basket and attempt to let the come to rest inside that basket.For me it helps cut down on the yips.
