"The wise screen writer is he who wears his second-best suit, artistically speaking, and doesn't take things too much to heart.  He should have a touch of cynicism, but only a touch. The complete cynic is as useless to Hollywood as he is to himself.  He should do the best he can without straining at it.  He should be scrupulously honest about his work, but he should not expect scrupulous honesty in return.  He won't get it.  And when he has had enough, he should say goodbye with a smile, because for all he knows he may want to go back."
