People, i.e. you and I, are inherently irrational much of the time; even those with sharp reasoning skills. And we're hardly ever able to see our own irrationality, tho we discern it in others constantly.

We're also ingenious; even those with poor reasoning skills can be ingenious.

Realizing that you're adrift in an ocean of ingenious, irrational beings will not increase your happiness, so do your best to forget what I told you, and return to pondering how miraculous you are ;-)
