Here’s the thing: In every corporation and every politician, in every university, in every country, sooner or later, you get envy. You’re struggling, and you see another organization in your space. And the tendency—if you don’t have a purpose that you can articulate—is to strike out on a mission to become a worse them. Purpose says: “Wait a minute; stop it; if we try to be like them, the best we’ll ever be is a worse them. It’s the best we’ll ever be. So instead of being a worse them, let’s become a better us.” Well, you can’t become a better us unless you know what us is.
