"Too much that we do is done at the expense of something else, or somebody else. There is some intransigent destructiveness in us. My days, though I think I know better, are filled with a thousand irritations, worries, regrets for what has happened and fears for what may, trivial duties, meaningless torments - as destructive of my life as if I wanted to be dead. Take today for what it is, I counsel myself. Let it be enough...We are in the habit of contention - against the world, against each other, against ourselves."
Another piece of common sense from Wendell Berry.
