True Grit: The Surprising, and Inspiring, Science of Success

Angela Duckworth’s work suggests that perseverance is a predictor of success. During her graduate student days she created a “grit scale” which she subsequently tested throughout her career. She characterized “grit” as working hard and finishing what one begins and gives the example of Will Smith explaining in an interview that if he was in a competention on a treadmill, there would be only two outcomes: he would be the last one running or he’d die on that treadmill because he “will not be out worked.”
