"The world in which a man lives shapes itself chiefly by the way in which he looks at it, and so it proves different to different men; to one it is barren, dull, and superficial; to another rich, interesting, and full of meaning." - The Wisdom of Life, Arther Shopenhauer. To enjoy life you have to pay attention to it.
Everyone, 24-7, is paying attention to something. The trick is not to regret the choice.
Not to nitpick but that ain't necessarily so.
In meditation we study attention and do neat tricks with it.
One trick is a refinement of plain old concentration.
The other trick is breaking the habit of always paying attention to something.
That second one is especially neat.
