““Incremental theory’ people are different. Because they think of abilities as emerging through tackling challenges, the experience of failure has a completely different meaning for them: it’s evidence that they are stretching themselves to their current limit. If they weren’t, they wouldn’t fail. The relevant analogy here is with weight training; muscles grow by being pushed to the limits of their current capacity, where fibres tear and reheal. Among weightlifters, ‘training to failure’ isn’t an admission of defeat – it’s a strategy.””
