The only way to resonate at a level that persuades is to know who you are addressing. If it's true that the Audience is the hero, you need to spend time thinking about them. Really getting to know them to the point it feels like they are a friend. May times we picture our audience as a large clump of strangers. Instead, you need to picture them as individuals standing in line to have a personal conversation with you. It's easy to persuade a friend, you need to think about your audience until you know them as a friend.
