There's no such thing as nothing.
Acting is the ability to live truthfully under the given imaginary circumstances
An ounce of behavior is worth a pound of words.
That which hinders your task is your task.
With a developed imagination there's no place you can't go.
Acting in a scene is like paddling a canoe from a pebbly beach on to the river, the writer builds the canoe, and the actor provides the river. The river is the actor's thoughts and emotions.
