“They have optimism and confidence. Because they are optimistic and confident, they react to setbacks not by getting discouraged and giving up, but with persistence. Their attitude is, “I’m not playing well right now, but when I put it all together [or our team puts it all together], I’ll really be something. I can beat anybody.” Because they persist, they get better. Because they get better, they experience success. And that success reinforces their optimism, their confidence, and their respect for their own talent. That’s the virtuous circle.”
