The novel you know as Pride and Prejudice began life under a different title: First Impressions. My father offered it to a publisher who turned it down sight unseen.
For years it sat in a drawer. When I finally returned to it, I cut, rewrote, and renamed — and discovered that a book sometimes has to fail before it can become itself.
If you are staring at a draft that isn’t working, take heart. Sometimes the kindest thing you can do for a story is to set it on fire and rebuild from the ashes.
