Expert writers do it very differently. Consider how my coauthor and I put this book together. First we had to figure out what we wanted the book to do. What did we want readers to learn about expertise? What concepts and ideas were important to introduce? How should a reader’s ideas about training and potential be changed by reading this book? Answering questions like these gave us our first rough mental representation of the book—our goals for it, what we wanted it to accomplish.
