The goal of every first-time novelist is to see her book between covers. The paradox is that when we make this goal more important than the story, we tend to find ourselves stuck.
The good news for first-time novelists is that the barriers to publication have blown wide open. Self-publishing used to have a terrible stigma attached to it. It was the domain of desperate wannabes who were willing to be bilked out of ten grand in order to quell their vanity and have something to show their friends. Those people still exist, and are never going away. But with the traditional publishing world crumbling fast, new models for publishing are springing up, and legitimate platforms are presenting themselves to support first-time novelists like never before.
So, return your focus to the task at hand. Write your book. While you’re writing, new opportunities are being designed to present your first novel to the world.
