You are an irrational person. Yes, you.
That’s not an insult. If you can read this, you’re a human being — and that makes you irrational. In fact, I believe — in all seriousness — that every human being is just a little bit insane. Some form of insanity is a universal “birth defect” among us.
One of the biggest mistakes we make in life is assuming we’re rational. What’s worse, we notice that other people seem irrational and stupid, but almost all of us believe we’re the exception. My way of looking at the world is right and rational. Your way is wrong and irrational. (You probably have evil motives, too.)
You are the hero of your own story. In your own mind, you believe you’re making rational and smart and sane decisions. You believe you have good motives, at least within the context of however you’ve justified your own actions.
I do exactly the same thing. And our mutual blindness about this whole charade leaves us with warped perceptions of the world around us — and of each other.
