American psychologist, researcher of resilience and author of the theory of grit.
Failure is not an end. It is a reformulation. A person with grit sees failure as information, not a verdict.
IQ is only part of the equation. People with grit achieve more than those with talent alone.
Grit can be cultivated. It is not an innate trait but a skill that must be practiced every day.
Grit is passion and perseverance toward very long-term goals. It is the inability to give up.
