I don't think there is a secret. We definitely didn't find it. We discovered that it's work. But we already knew that. It was very fun to actually walk through our time together and see the timeline presented. When we started the process, we didn't really think we had a book. But in that sense, it was fun to actually have someone to walk us through so that we didn't have to try to put a framework to it since we didn't know what the framework was. But from talking to [co-author Hilary Beard] together and individually, she was able to say, "This is actually a book.” We didn't start out to write a 300-page book. We started out with something much simpler and it morphed into that. It was fun to be able to talk about our journey together, because that's what it is, it is a journey.
