Keep your bum glued to the chair. It’s extraordinary how, if a piece of writing is going badly—and sometimes even when it’s going well—other activities become steadily more attractive. Not just getting up to make endless cups of coffee either—even cleaning out the cupboard under the sink seems suddenly a fun thing to do. Resist! You’ve got to turn up, on time, at the blank page or screen, and then just stay there. That way, if the Muse does decide to pay you a visit, at least she’ll know where to find you.
