"The pages are still blank, but there is a miraculous feeling of the words being there, written in invisible ink and clamoring to become visible." Vladimir Nabokov (1899-1977)
There's a humility in this view point. And it seem to me to be the true one: the view of writer as the servant of the story--whose job is to discover as much as create. To listen and transcribe. The writer basically as scribe.
It's about the story, not about you the writer.
Do you ever have the feeling that if you don't show up and get those words visible--QUICK--they might just give up on you and go somewhere else to someone who will?
That's motivation to keep showing up. Being available, there, to listen to whatever's happening that day. To whatever your characters are talking about.
As one editor told me once "Put your characters in a room and listen to what they say."
It's like a show going on in your computer every day. Why would you want to miss that?
