Those words from my instructor still ring in my ear every time I find myself slipping back into the not-concentrating mode. I must concentrate as part of my aiming and force myself to see that point behind the object ball which I aim at.
Mark Your Cue?
There almost as many systems for aiming as you can find in opposing players. Each brings their own variant to the game. Remember, it's not Fire!, Aim, Ready. Just the opposite. These tips will help you get the right flow.
Look at the shot while you are standing and align yourself in its direction. You want to be able to "“see" the shot without another ball jutting into the intended path. Your goal is to see the shot without having to rely on a “ghost ball”. You should be able to see the line of the shot; the line the cue ball must travel to hit the object ball or rail. See the line, not some imaginary ghost spot. Choosing that exact line will help you determine what you want to accomplish with this shot, relying on your current level of skill and various aiming ajustments to compensate for throw, squirt english etc.
