Angela Lee Duckworth’s TED Talk “Grit: The Power of Passion and Perseverance” discusses the significance of grit in achieving success. Duckworth defines grit as a combination of passion and perseverance over the long term. Through her research, she found that grit, rather than talent or intelligence, is the most reliable predictor of success in various fields, including academics, sports, and business. Duckworth emphasizes the importance of cultivating grit in individuals, especially in children, and provides insights into how grit can be developed and nurtured. She argues that by fostering grit, individuals can overcome challenges, setbacks, and failures, ultimately leading to greater achievements and fulfillment in life.
