Use the reverse summary technique to outline your book
One of the biggest pitfalls in the world of writing nonfiction is the risk of being overwhelmed.
That’s true of authors as well as readers — when you sit down to write your book, you can quite easily find yourself staring at a virtual pile of knowledge and no clear path to sort it.
Enter the reverse summary technique, as explained by Esbe van Heerden.
In it, you work backwards, obviously — the first step is to summarize your book, then create a table of contents from that, and so on.
Van Heerden has the subsequent steps and an explanation of each on The Creative Penn.
