Heard from two different authors, both excellence marketers, in the past two weeks:
Ancillary products and spin-offs.
The advice, in a nutshell, is don’t write just one book. Write a second book. Write a sequel. Write a pamphlet. Make a poster from one of the concepts in the book. Write a cookbook.
This is how authors make a living writing. They don’t simply write once. They write, and they write again. For their fans.
This is advice I’m taking to heart.
