The mind, in short, works on the data it receives very much as the sculptor works on his block of stone.
William JamesFailure, then, failure! so the world stamps us at every turn. We strew it with our blunders, our misdeeds, our lost opportunities, with all the memorials of our inadequacy to our vocation. And with what a damning emphasis does it then blot us out! No easy fine, no mere apology or formal expiation, will satisfy the world's demands, but every pound of flesh exacted is soaked with all its blood. The subtlest forms of suffering known to man are connected with the poisonous humiliations incidental to these results.
William James
