Not Every Gain Requires Someone Else's Loss

Zero-sum thinking — the idea that every winner creates a loser — is one of the most limiting mental models. In many areas of life, both sides can gain from the same interaction. A good negotiation, a strong partnership, a well-run team: these create value that didn't exist before. When you stop viewing every situation as a pie to divide and start looking for ways to grow the pie, collaboration becomes possible and competition becomes less bitter.
