"What is the worry trick? The trick is this: you experience doubt and treat it like danger. We all live our lives as if we know what's going to happen.
People sometimes talk about the "fear of the unknown" as if it were a special category of fear. Everything about the future is unknown! It's not the unknown that people find scary. It's when they consider the future and think that they do know what will happen, and it's going to be bad. That's when they get afraid."
