As an actor, I'm familiar with having bursts of energy, where you're giving things a try, and then you have down time.
“Be thou incapable of change in that which is right, and men will rely upon thee. Establish unto thyself principles of action; and see that thou ever act according to them. First know that thy principles are just, and then be thou.”
“Good directing is about getting the performance to be just what's right for the movie.”
