“The future is shaped by men and women with a steady, even zestful, confidence that on balance their efforts will not have been in vain. They take failure and defeat not as reason to doubt themselves but as reason to strengthen resolve. Some combination of hope, vitality and indomitability makes them willing to bet their lives on ventures of unknown outcome. If our forebears had all looked before they leaped, we would still be crouched in caves sketching animal pictures on the wall.”
