I feel like any actor should always be thinking about how to serve the story. The thing to be cautious of is trying to make too much of your "moment," or whatever. The story is a lot bigger than you, and you're there to help it along. The thing to think about is whether what you're doing is true to the moment and where the story's going, rather than going, "Here are my scenes. What can I try and do to make the most of them?"
