The real wisdom here isn't simply that loving your work feels better—it's that the *same effort* transforms entirely based on your internal relationship to it. A surgeon performing her hundredth routine procedure might experience it as rote labor, while an enthusiast restoring vintage cars works through identical hours of concentration and physical strain as pure joy. Sinek's distinction matters because it suggests stress isn't really about how hard you're working; it's about the absence of meaning. That reframes the problem: when you're exhausted and bitter, the answer isn't necessarily to work less—it might be to find work that matters.
