"Treat strategic failure as skill-building, not wasted time Daniel Litt reflected on how his mathematical ability at 41 far exceeds what it was 20 years ago, even though peak-prize eligibility has passed. He attributed this not to raw talent but to accumulated experience: 'attempting to solve a problem and failing — but failing in a way that when a similar problem comes up later, I will have better intuition about what avenues might be productive and what might not be productive.' This reframes failure from a signal to stop to a mechanism of calibration, meaning the person who has failed thoughtfully on hard problems is better equipped than someone who only attempted easy ones.
