Pioneering psychologist, Angela Duckworth, shows anyone striving to succeed—be it parents, students, educators, athletes, or business people — that the secret to outstanding achievement is not talent but a special blend of passion and persistence she calls “grit.” Drawing on her own powerful story as the daughter of a scientist who frequently noted her lack of “genius,” Duckworth, now a celebrated researcher and professor, describes her early eye-opening stints in teaching, business consulting, and neuroscience, which led to the hypothesis that what really drives success is not “genius” but a unique combination of passion and long-term perseverance.
