Good point, duckie. My experience is similar to yours. One of the pool-related things I do is cue repairs. In earlier days of performing this service for money it was very distracting to have a customer looking over my shoulder and asking me questions while I was working on his/her cue. Over time, I learned how to answer the questions and fade the distraction all at the same time. It was necessary to learn to do this in order to keep my fingers attached and keep my customers coming back, as well.
Learning that skill then transferred over to my pool game. I discovered that being in "the zone" largely means having true focus. And I'm not talking about focusing with the mind, I'm talking about focusing with the eyes. If you always keep your eyes on your work, it's much easier to keep the bulk of your mental attention there, too.
Watch the great players. Their eyes almost never leave the table; even when they're not the one shooting.

Not too long ago I relearned this trick of never taking your eyes off the table.
Originally it came to me the night before playing in a big 9ball tournament up in Missoula back in the early 80's. I was warming up the night before playing some $10 9ball with another payer and, for reasons unknown, it came to me that the longer I focused on the table the more info/data I was giving my wetware (brain). That, in turn, allowed my brain to give more precise instructions to my body for getting into proper shooting position for exactly the shot I wanted to execute and how I wanted to execute it. And so I played that tournament always keeping my eyes on the table (and not the cute bar maids) and shot really well.
