Visualize the reader experience by adding word counts to your ToC With one small adjustment, your ToC will become an x-ray view of your book’s “takeaways over time,” allowing you to visualize, debug, and improve its reader experience. You do this by adding word counts to the titles of your sections and chapters, allowing you to see how many words (and thus how many minutes — 250 words per minute is typical) are sitting between any two pieces of value. These word counts will be removed prior to publication, but they’re invaluable while the book is in development.
