The real sting here isn't about accepting different talents—it's about recognizing that our *measurement systems* are often arbitrary tyrannies we mistake for universal truth. We castigate ourselves not because we lack ability, but because we've internalized someone else's yardstick as the only one that matters. A child labeled "bad at math" in third grade might spend decades avoiding numbers, never discovering she excels at statistical thinking—because early tests measured speed and procedure, not reasoning. The quote's power lies in its quiet indictment of how institutions and cultures hand down these limiting verdicts as if they were scientific fact rather than particular choices about what to value.
