A wonderful trick I was taught early on in my career was to think of the introduction as the beginning of a movie. What do you want people to “see” first? The camera sometimes can show multiple scenes at once. Other times it focuses on a specific something or someone and then zooms out. And other times, vice versa. The key is to bring people into your world—whatever that world is—and explain what it’s like.
