Mindset — Carol S. Dweck (2006)

Carol Dweck's Mindset introduced the concept of "growth mindset" vs. "fixed mindset" — the distinction between believing that abilities can be developed through dedication versus believing they are fixed traits — which has become one of the most widely applied frameworks in education, coaching, and management worldwide. Dweck's research demonstrates that how people think about the nature of intelligence predicts achievement more than actual measured ability.
