A director told me the number one "skill" needed in actors is: the ability to take directions.
How pliable are you? Must you do everything the director says? No. Directors are human, too. Fallible creatures. But if an actor's response to every note is simply: "No," "I don't want to do that," "That's not what I want," "Yes, but...," then the director will tire of working with that artist.
