Everyone tells you to write what you know. It’s the tried-and-true advice every writer hears at some point in her career. But to take my writing to a deeper level, I’ve found that a better practice is to simply write what frightens you, haunts you, even. I now keep a sign on the bulletin board in my office that reads: 'Write What Scares You.' I’ve learned that tapping into the hard stuff — whether it’s the fear of loss or a boogeyman lurking in childhood memories — is what ultimately gives a story the power to leap off the page and grab you by the collar.
