Is Grit the Key to Long-Term Success? Angela Lee Duckworth Explains

In this brief TED Talk, psychology researcher Dr. Angela Lee Duckworth argues that grit — defined as passion and perseverance toward long-term goals — is a stronger predictor of success than IQ, social intelligence, or physical health. Duckworth describes grit as the stamina to stick with your future year after year, treating life like a marathon rather than a sprint.

“In all those very different contexts, one characteristic emerged as a significant predictor of success. And it wasn’t social intelligence. It wasn’t good looks, physical health, and it wasn’t IQ.

It was grit.

“Grit is passion and perseverance for very long-term goals. Grit is having stamina. Grit is sticking with your future, day-in, day-out. Not just for the week, not just for the month, but for years. And working really hard to make that future a reality.

Grit is living life like it’s a marathon, not a sprint.”
