When you work as a writer who basically has to sit in front of a computer and type all day long, day in and day out, sometimes you just cramp. Writer's cramp is really frustrating because it means nothing is coming out and the clock is ticking and the boss gets more and more worried. My little trick when inspiration is missing is to play music in the background. Really soft so as to not be disturbing, but just enough to make me relax and focus. It works for me!
