In 12 Rules for Life, Jordan Peterson gets to a point that is paramount for healthy living:
“That’s how you deal with the overwhelming complexity of the world: you ignore it, while you concentrate minutely on your private concerns. You see things that facilitate your movement forward, toward your desired goals. You detect obstacles, when they pop up in your path. You’re blind to everything else (and there’s a lot of everything else—so you’re very blind). And it has to be that way, because there is much more of the world than there is of you. You must shepherd your limited resources carefully. Seeing is very difficult, so you must choose what to see, and let the rest go.”
