Pessimistic prophecies are self-fulfilling. - Martin E P Seligman

"I WAS THE CATCHER for the Lake Luzerne Dodgers, a catcher with meager talent, a catcher in awe of Danny and Teddy. Danny was the first baseman and Teddy, the coach's son, was the left fielder. They were natural athletes: they could hit fastballs (a small miracle of hand-eye coordination that I never mastered), and they glided around the base paths with the grace of gazelles. They were, to a ten-year-old who was batting .111, the embodiment of beauty and summer and health. As I drifted to sleep at night, it was often with the image of Danny, horizontal and three feet off the ground, spearing a line drive, or of Teddy stretching a single into a double by slipping under the tag. In the early hours of a chilly, August, upstate New York morning, my father woke me. "Danny's got polio," he said. A week later Teddy got it too. My parents kept me indoors, away from other kids. Little League was suspended, the season unfinished. The next time I saw Danny, his throwing arm was withered and he couldn't move his right leg. I never saw Teddy again. He died in the early fall. But the next summer, the summer of 1954, there was the Salk vaccine. All the kids got shots. Little League resumed. The Lake Luzerne Dodgers lost the opening game to the Hadley Giants. The fear that kept us housebound melted away and the community resumed its social life. The epidemic was over. No one else I knew ever got polio."

The optimists believe defeat is just a temporary setback.

explanatory style is the great modulator of learned helplessness. Optimists recover from their momentary helplessness immediately. Very soon after failing, they pick themselves up, shrug, and start trying again. For them, defeat is a challenge, a mere setback on the road to inevitable victory. They see defeat as temporary and specific, not pervasive. Pessimists wallow in defeat, which they see as permanent and pervasive. They become depressed and stay helpless for very long periods. A setback is a defeat. And a defeat in one battle is the loss of the war. They don’t begin to try again for weeks or months, and if they try, the slightest new setback throws them back into a helpless state.
