Acting is ephemeral. You can't hang it on a wall. You can't throw it off. And you can't bring it out of a closet. It's there one night and it's gone the next, at least with stage acting anyhow.
You're out there on a high wire without a net, and that's the way actors operate. They have to be fearless about how they work and they have to create a life for the audience in 90 minutes and make them believe.
