“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.”
