Most authors, at least in my experience, have a writing process of one form or another. Some people insist that they can’t write unless they’re in a certain mood, others feel most comfortable writing for set hours in the day. Personally, for me to get any writing done, I have to abide by a very strict set of rules. These mostly involve setting up my surroundings to encourage a creative mind-space (and usually sitting up in bed against a gargantuan stack of pillows).
