Marketing is not my cup of Earl Grey. As soon as I open my mouth, I have visions of all the overbearing sales people I've ever met mocking me. However, I realize it's nutty to write for publication and never talk about it. I'm not a hermit. I just like to write.
So, what to do? Be the reader.
I've started sitting on the floor with a picture book and thinking about color and text choices. I'm spending time (minutes) on particular characters and/or characteristics on each page like a child would do.
Olivia by Ian Falconer is a good book to try this with. Black, white, and splashes of red tell the story in addition to words. I love it. The words and illustrations focus the attention, but also let an active imagination wonder what will happen next.
When I became the reader of my books instead of the author, the marketing monkey got off my back.
