"I believe the only way a writer can keep himself up to the mark is by examining each story quite coldly before he starts writing it and asking himself if it is all right as a story. I mean, once you go saying to yourself, 'This is a pretty weak plot as it stands, but I'm such a hell of a writer that my magic touch will make it okay,' you're sunk. If they aren't in interesting situations, characters can't be major characters, not even if you have the rest of the troop talk their heads off about them."
