hi cmays
think thats a bit like having one swing though as you walk up to the ball. like slow and smooth, or if a pich, thinking "soft hands" or like you said trying to imagin the shot before you hit it and almost see it in your mind.
think if you only have one though your mind dont get confused about the many things that can go wrong, like the bunker 100yrds out from the green or the water to the right, think one thing only and you swing better through the ball
