I don't care. I mean, I've been stupid in the past, and I've learned from that. Some actors actually think about what they're going to talk about during the interview--they read up and meditate and plan quotes and get all inspired. It's very smart, but it's so planned. I never think to do that.
They mustn't know my despair, I can't let them see the wounds which they have caused, I couldn't bear their sympathy and their kind-hearted jokes, it would only make me want to scream all the more. If I talk, everyone thinks I'm showing off; when I'm silent they think I'm ridiculous; rude if I answer, sly if I get a good idea, lazy if I'm tired, selfish if I eat a mouthful more than I should, stupid, cowardly, crafty, etc. etc.
The man whose whole life is spent in performing a few simple operations, of which the effects are perhaps always the same, or very nearly the same, has no occasion to exert his understanding or to exercise his invention in finding out expedients for removing difficulties which never occur. He naturally loses, therefore, the habit of such exertion, and generally becomes as stupid and ignorant as it is possible for a human creature to become.
I have wanted to kill myself a hundred times, but somehow I am still in love with life. This ridiculous weakness is perhaps one of our more stupid melancholy propensities, for is there anything more stupid than to be eager to go on carrying a burden which one would gladly throw away, to loathe one’s very being and yet to hold it fast, to fondle the snake that devours us until it has eaten our hearts away?
For the wise man delights in establishing his merit, the brave man likes to show his courage in action, the covetous man is quick at seizing advantages, and the stupid man has no fear of death.
Actors aren't stupid, mostly, and if there's a sensibility and an aesthetic that a director's going for, if you're aware of that too, you can do things to help that.
Teach success before teaching responsibility. Teach them to believe in themselves. Teach them to think, 'I'm not stupid'. No child wants to fail. Everyone wants to succeed.
