The way it’s written and the story it tells.
The way it’s written is for other writers.
The story it tells is for your readers.
It’s important to me to write in a way that speaks to other writers in the way a good composer speaks to other musicians. The listener, the audience, hears the music and enjoys it. The musician reads or hears the music and asks the question–How did he do that?
Writers know that it’s not story that matters, but how the writer writes it.
Readers don’t care how it’s written, they care only about getting the story.
To me, if you can do both–tell a story and write it so other writers ask how it you did it, you’ve achieved something.
