The real wisdom here isn't about accepting failure—it's about recognizing that fear, not actual wrongness, is what paralyzes us. Most people assume confident people simply make fewer mistakes, but McIntyre suggests the opposite: they've made peace with error itself, which paradoxically makes them *more* likely to act decisively and learn from setbacks. Watch a skilled surgeon or negotiator, and you'll notice they move with assurance not because they've memorized every outcome, but because they've accepted that uncertainty is the price of meaningful work. That acceptance, oddly enough, is what allows them to think clearly when stakes are high.
