Human beings are largely engaged in wasting enormous amounts of psychic energy in attempting to do things that are quite impossible. All sensible people therefore begin in life with two fundamental suppositions. You are not going to improve the world. And you are not going to improve your self. You are just what you are. And once you have accepted that situation, you have an enormous amount of energy available to do things that can be done. And everybody else looking at you from an external point of you will say “My god, how much so-and-so has improved!”
Alan Watts in discussion on the veil of thought. Listen to the full talk.
