Most writers dislike marketing. They dislike anything that takes them away from their writing, but marketing is toward the bottom of the list.
I don’t want to turn into a plaid polyester-wearing used car salesman! I just want to write! Besides, I have a blog, and it just lays there, doing nothing. How will anyone find it? What difference will it make, anyway?”
I’m a writer who came at this from the world of marketing (the subject of most of my books) so I have a different perspective.
