" Optimism is a deadly vice of gigantic proportions lodged into the human psyche by Satan. It is the enemy of reality. We see a bad situation and optimism prevents us from extrapolating that. Instead we think, " Oh, it's bound to get better." So we plunge into the thicket, sure that it will thin, denied the aerial view that would show us the true, unacceptable horror of our lot. Perhaps optimism is good for prison escapees, who have no choice but to plod on. The rest of us are not well served. It poisons our judgment. "
