When kids tell their parents, “I’m not as smart as Eric,” or “I’m not as smart as most of the kids in my math class,” many parents will try to reassure their kids by saying, “Yes, you are. You’re just as smart as they are.” Bill takes a different approach. He tells kids that you only have to be smart enough to do something interesting in this world—which they are. He also tells them that he’s grateful for all the people in his field who are smarter than he is. They’re the ones who make up the theories and tests that allow him to make a living by helping people.
