Ive seen that video of efren playing at his local place, I know its crazy, but I'm not used to that.
Besides Ive tried so hard blocking and not thinking about things that are happening around me, but it didn't work. I miss the simplest shots if something bothered me and its always 100% always is outside of the table, and Ive tried telling the person who is talkative near my table that its annoying me, but that didn't help because I already feel bad for telling him that, and already put me out of my pace and out of my game too.
Most thing that annoys me as I said, is when i'm down on a shot, and at my sight a person walks by, I duno how to think to this, it just gets to my head very easily, is there any method of erasing everything outside of the table and not look at it somehow? even if you're aware of potential distractions, the guy who will walk next to you, or infront of you will happen all of a sudden.
Try focusing all your attention on the contact point on the OB. I don't mean "look" at the OB...I mean laser-focus your vision on the exact contact point for a minimum of 2-4 seconds before you shoot. If you have to look at the CB, start the 2-4 seconds of OB over again. We're talking about intense focus here, much more than you've ever probably done before. It takes some practice, but it pays off.
We think our eyes have a wide angle of peripheral vision, but that's because we normally move our eyes around to take in more information. Your actual peripheral vision is really very narrow...and it narrows even more the longer you're focused on an object. If you're really focused on the contact point of the OB you won't notice Peter Pan dancing on the rails near the pocket on a straight-in shot.
You'll also find that you begin to hear less of the background noise. If your brain is soley focused on the contact point of the OB it is using up nearly all of its sensory power...there's basically nothing left for hearing anything short of a bomb going off.
The downside is that it's very tiring until you get used it. But like an athlete, the more you do it, the longer you're able to before tiring.
