Where would we be without people brave enough to challenge the odds? If every entrepreneur, activist, and general listened to the predictions, what kind of world would this be? If every oncologist faced the facts of their diagnoses, no patient would ever be saved. If every team down in the fourth quarter believed they were beaten, there would never be any comebacks. If every RAF pilot had looked at the numbers in 1940—a one-in-ten chance of dying in each sortie—would Britain have been able to hold out?
