An ounce of behavior is worth a pound of words.
Every little moment has a meaning all its own.
The greatest piece of acting or music or sculpture or what-have-you always has its roots in the truth of human emotion.
Technique is something that you use if you need it. Otherwise, to hell with it.
That's very different, picking up the impulse instead of picking up the cue.
Acting is behaving truthfully under imaginary circumstances.
