For most of the rest of this book, I’m going to assume that you have something you want to talk about, whether it’s a lifelong passion, a topic you’re eager to dive into more deeply, or a project for work that you have to present. In the chapters to come I’ll be focusing on the how, not the what. But in the final chapter we’ll return to the what, because I’m pretty sure that everyone has something important they could and should share with the rest of us.
