Let’s say you’re on an elevator, the door opens, and someone you know steps in. She says, “I hear you’re writing a book. Wow, that’s great. What’s it about?”

Can you answer that question before you get to the next floor? You may be thinking, “Of course, I can. It’s my book, isn’t it?” Yes, but chances are you will be still be talking when the elevator door opens again. Completing this critically important sentence in 30 seconds or less is not easy. In fact, it takes most people quite a while to describe their books in a way that other people understand.
