So how does Oreo connect with writing? It is said that there are only 7 basic plots an author can write about (The Seven Basic Plots: Why We Tell Stories by Christopher Booker), but the different spin on the basics is what makes a different story. A sell-able story. An enjoyable story.
Is that not what an Oreo is?
A basic cookie with a cream middle that with slight variations entices new buyers.
As writers we want to make those slight variations of the 7 possible plots shine and sparkle, enticing new readers, and keeping our fans coming back for more.
