Acting is fun. Don't let that get around.
The greatest piece of acting or music or sculpture or what-have-you always has its roots in the truth of human emotion.
The truth of ourselves is the root of our acting.
The truth of your instincts is the root of your foundation.
That's very different, picking up the impulse instead of picking up the cue.
Don't be an actor. Be a human being who works off what exists under imaginary circumstances.
