Knowing your target audience is one of the most important things you can do for the success of your book. Ideally, this should happen even before you start writing, or at least in the early drafts. Yet, when I ask authors who their target audience is, 90% of the time they say, “My book is for everyone!”
The problem is, if you try to write a book for everyone, you end up writing a book for no one—or worse, a book only for yourself.
