The following was taken from The Fire in Fiction by Donald Maass:
"A masterpiece novel may be singularly inspired, and it certainly can be a once-in-a-career event. But even so, it is not magic. It may feel that way to the author. He may hype its close-to-my-heart genesis and confess in The Writer on NPR that the manuscript wrote itself.
It disappoints me when authors perpetuate the myth that writing is magic. Some allow it to be so. It's a a shame that those writers fail to understand their own process. What's wrong with that? What's wrong is simply that magic is unpredictable. A method that's mysterious cannot be repeated.
I believe that passion is available to every author, every time she sits down to write. Every novel can be inspired. Every scene can have a white-hot center. it is not a matter of conjuring demons, being obsessed, or just plain luck. The passion that inspires great fiction can be a writing technique as handy and easy to use as those with which all fiction writers are familiar. Passion can be a practical tool."
