Whatever you decide is your motivation in the scene, the opposite of that is also true and should be in it.

Humor [in a scene] is not jokes. It is that attitude toward being alive without which you would long ago have jumped off the 59th Street Bridge.

There's only one reason why a character drinks: to seek confrontation. To fight for what they want in ways normally denied them.

To go into acting is like asking for admission to an insane asylum. Anyone may apply, but only the certifiably insane are admitted.

The life of an actor is a bit easier to take if you admit you're bonkers.

Competition [in a scene] is healthy. Competition is life. Yet most actors refuse to acknowledge this. They don't want to compete. They want to get along. And they are therefore not first-rate actors.

An actor must make his needs (goals, wants, objectives) so strong that he is willing to interfere with the other actor in order to get what he needs. Interfering means getting in their way so that what you want is stronger than what they want.
