“I don’t consider myself especially smart. Over the years, I have met many people born with what seemed to be a photographic memory, a gift for learning effortlessly. One of my elementary school classmates could hear something once and remember it forever. That wasn’t me; it has never been me. But even as a young child, I understood something critical: What I lacked in natural ability, I could make up for in effort. I could work harder, put in more hours, do more, and do it with greater care.”
