E. 331: AJ Harper on How to Write a Book People Actually Read

Most experts begin writing a book by thinking about everything they want to say. But according to AJ Harper, that is exactly where authors can go wrong. A book isn’t about something. A book is for someone.

In this conversation, AJ explains why the reader’s transformation should guide every decision you make, from which ideas belong in the book to how you organize and market it. We talk about identifying what your reader wants, understanding what they believe is standing in their way, and creating a promise you can actually deliver by the final page.

AJ also shares why experts should test their ideas before putting them into a book. It is not enough for your process to have worked for you. You need to know whether it can create change for other people, where they get confused, and what they need to keep moving forward.

We also get into how a book can support your business without turning into a giant advertisement. AJ explains how to choose one clear next step for readers and plant subtle seeds through useful stories and examples that serve the book first.

AJ Harper is an author, editor, and publishing strategist who helps writers create books people dog-ear, underline, and rave about. She is the author of Write a Must-Read and the longtime writing partner of Mike Michalowicz, collaborating on books including Profit First, The Pumpkin Plan, and The Money Habit. Together, they co-host the podcast Don’t Write That Book.

AJ’s approach is such an important reminder that writing a great book is not about proving how much you know. It is about choosing the right ideas, delivering a meaningful transformation, and creating something readers will finish, use, and tell other people about.
