In displaying the psychology of your characters, minute particulars are essential. God save us from vague generalizations! Be sure not to discuss your hero's state of mind. Make it clear from his actions. Nor is it necessary to portray many main characters. Let two people be the center of gravity in your story: he and she.
Anton ChekhovA litterateur is not a confectioner, not a dealer in cosmetics, not an entertainer. . . . He is just like an ordinary reporter. What would you say if a newspaper reporter, because of his fastidiousness or from a wish to give pleasure to his readers, were to describe only honest mayors, high-minded ladies, and virtuous railroad contractors.
