When we, like God, set out to create a universe — a book, an opera, a new business venture — the same principle kicks in. Our screenplay resolves itself into a three-act structure; our symphony takes shape into movements; our plumbing-supply venture discovers its optimum chain of command. How do we experience this? By having ideas. Insights pop into our heads while we're shaving or taking a shower or even, amazingly, while we're actually working. The elves behind this are smart. If we forget something, they remind us. If we veer off-course, they trim the tabs and steer us back.
