Go into the streets, into the slums, into the fashionable quarters. Go into the day courts and the night courts. Become acquainted with sorrow, with many kinds of sorrow. Learn of the wonderful heroism of the poor, of the incredible generosity of the very poor—a generosity of which the rich and the well-to-do have, for the most part, not the faintest conception. Go into the modest homes, into the out-of-the-way corners, into the open country. Go where you can find something fresh to bring back to the stage.
