I think the most important thing I learned from Stephen King I learned as a teenager, reading King’s book of essays on horror and on writing, Danse Macabre. In there he points out that if you just write a page a day, just 300 words, at the end of a year you’d have a novel. It was immensely reassuring - suddenly something huge and impossible became strangely easy. As an adult, it’s how I’ve written books I haven’t had the time to write, like my children’s novel Coraline.
One of my journalism professors from St. Bonaventure once gave me this page-a-day advice, and ever since then, it’s something I’ve stuck to. It is by far the best piece of writing advice I’ve ever heard, and it is something I share every time anyone asks.
