The toughest parts of the shooting schedule for me are the days between working, when you've nothing to do but wait. There is only so much time you can spend on a script before it becomes so rehearsed that your performance becomes rigid and immovable on the day of, so one has to occupy one's time in some fashion. For me, those interim days are usually spent exercising, exploring, learning to cook something edible, and working on my own creative endeavors.
