The CO of FOCOCO

Concentration as "Fascination of the mind for the object upon which we focus"

Attention is the process by which we uses our senses to perceive the world. Focusing our attention means that we become aware of one thing or one set of things at the exclusion of others. As discussed before this Focus can be internal or external

Concentration is something else. It is when we sustain our attention on selected stimuli for a long period of time. That is the attention span.

You cannot concentrate by telling yourself: Now, I will concentrate! (And concentration does not mean staring at something). There is also a clear link between concentration and switching focus styles. If we use of lot of mental energy to select the right focus style and to switch between one style and the other, our concentration will fade.

Top performers sustain a degree of concentrated focus. Their mental game allows them to retain balance and the belief that “it ain’t not over til it’s over” . They trust the process.
Someone said of Tiger Woods: Apart obviously his immense talent, what he has is a total commitment to his mental game. Not just once in a while or only when things are going good but on every shot his attention is focused

Here is a story:
One time, Woods missed a short birdie putt on a par 5 hole. In disgust, he whiffed his putter thorough mid air. He tapped the next one in, but he was now four shots behind the leader with four holes to play. A tough task to make up.
On that next hole, Tiger went to the tee and went through his pre-shot routine. (All good golfers have a pre-shot routine of lining up the shot, envisioning what they want to do and the flight of the ball.) Then they step up and address the ball. Tiger did this. As he started his back swing, a car full of hecklers drove by screaming and honking the horn. Tiger froze, right in the middle of his back swing, stepped back from the ball, smirked a smile, regained his composure, and went through his pre-shot routine all over again. He then stepped back up to the ball, took his swing and knocked it right in the hole for a hole-in-one.
