While that sounds good on paper, it's not practical or realistic to "imagine" playing pool for hours. You'd be way better off watching a lot of classic matches and envisioning yourself taking their shots and absorbing their confidence as they play. Is way more effective.
Really....and you did read the basketball study about those that used visualization improve more than those that did not?
How much research into the benefits of visualization did you do before you made this statement.
And who said hours?
Ever raced? One of the things motorcycle racers do is sit in a chair with a stop watch. They click the watch and visualize a lap of a track. When the finish line comes up, in their mind they click the stop,watch. The goal is to have the same lap time as in real life.
Visualization works and it's much better then watching what someelse ones does. Why would I imagine myself as someone else making shots and not me being that person making shots.
I can not play like someone else, so why would I want to imagine, visualize, playing a style of pool that's not me, but for someone else?
No one else has a stroke like mine, why would I want to visualize a stroke that's not mine? That is more harmful them helpful.
This is one of the problems in pool.....thinking you have to imitate the style of play of others, hence all the sellers of systems, personal style of play implying that's is THE way to play and very few about practice and what it really takes to improve, which is proper practice over a life time. Few are willing to make the lifetime commitment part. They want it now.
