Experiences yield dividends because we humans have memory. We don’t start every day with a blank brain, like characters in so many sci-fi movies. We wake up every morning preloaded with a bunch of memories that we can access at any time—mainly to get around and navigate the world. When you face a large rectangular panel with a protruding round knob, you don’t ask yourself, What is this thing? No, you know it’s a door. And you know how to open that door. So there’s a huge dividend from having once learned what a door is—think of all the doors you can open!
