There is a growing body of evidence that suggests that if we never let our mind wander or be bored for a moment, we pay a price — poor memory, mental fog, and fatigue.

one of the worst features about worrying is that it destroys our ability to concentrate.

The person who reads too much and uses his brain too little will fall into lazy habits of thinking..

Never let the brain idle. ‘An idle mind is the devil’s workshop.’ And the devil’s name is Alzheimer’s.

The greatest lapses in concentration come when we allow our minds to project what is about to happen or to dwell on what has already happened.

Every second you spend thinking about the next moment, you avoid embracing the present.
Ensure your life isn’t lived entirely in your head.

Sixty minutes of thinking of any kind is bound to lead to confusion and unhappiness.

Of course, nobody likes to be bored. But by abolishing any chance of being bored we have also lost the times we used to have to think and process.

When we waste time, we’re procrastinating. When we can’t manage our attention well, we’re distracted. And when we don’t cultivate our energy levels, we’re tired, or “burned out.

When we don’t master our minds, we risk building our lives on a foundation of flimsiness.

If you slacked off your attention for even a moment, you could stall the entire line — forcing workers into an unnatural combination of boredom and constant attentiveness.

We must not think too much: people go mad if they think too much.

Psychologists call this “decision fatigue”: the more choices we are forced to make, the more the quality of our decisions deteriorates.

Anyone who has a two hundred-plus IQ runs the risk of just hanging out because you get too involved in your own thoughts and you just want to sit there and think about .
