Listen, Stephen King used to write in the washroom of his trailer after his kids went to sleep. Harlan Ellison wrote in the stall of a bathroom of his barracks during boot camp. Elmore Leonard got up at 5 AM every morning to write before work.Every time my alarm goes off at 5 AM and I don’t want to get up, or I would rather sit down after work and play a videogame, I think about those guys. Take care of your family. They need you and love you. Make time for them. Then stop screwing around and finish your damn book.
