“First, you have to psych yourself into a good night’s sleep, after having arranged a fool proof wake-up call. Second, you have to be sure of your transportation arrangements when you do get up in the morning because your time is their money, and if you don’t know how you are getting to the studio or the location on time, you won’t have the job when you do get there, late. Establish where to go (the venue of your shoot might always be changing) and then mentally rehearse your journey there as if it were the first scene in the film. You’ve got to get your own act together before the camera’s act can begin. Being prepared isn’t just for the demands of your part; it’s also for the demands of the studio or location. You must get your bearings and establish where to go and what to do when you get there.”
