“ Please don't entertain for a moment the utterly mistaken idea that there is no drudgery in writing. There is a great deal of drudgery in even the most inspired, the most noble, the most distinguished writing. Read what the great ones have said about their jobs; how they never sit down to their work without a sigh of distress and never get up from it witout a sigh of relief. Do you imagine that your Muse is forever flamelike -- breathing the inspired word, the wonderful situation, the superb solution into your attentive ear? ... Believe me, my poor boy, if you wait for inspiration in our set-up, you'll wait for ever. ”
