Remember Miss Kingsley?
Do you remember Miss Kingsley, your fourth or fifth grade teacher, who tried to excite you with information about grammar and writing?

One of the important points she undoubtedly made—but is often forgotten today in this world of self-published e-books—was the importance of including more than one topics in your publication’s outline levels.

Let’s take a major topic, perhaps a discussion of the states making up the United States. If you want to break that topic up with a subhead, you must include two subheads. In the states example, you could include a subhead entitled: “States West of the Mississippi” and another subhead entitled “States East of the Mississippi.”

Just one subhead isn’t enough—there has to be at least two subheads for each level of your publication.

If you break a stick in half, you get two parts—a left and a right. Both warrant a subhead.
