i think we can use this in every aspect of life, not just acting...
"What confounds me is: Why do actors so love to make the negative choice? Look how you fought like a tigress to hang onto your negative choices! And negative choices don't do you any good; they drown you, obliterate you; they keep any auditor from knowing who you are. They're only one side of you, and they're not the side that motivate your life! You are motivated by dreams, not negative realities. Reality creates the problems, dreams are how we deal with them. Dreams are why we stay alive. If you leave out your dreams, you leave out the very best part of you as a human being."
