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 ChekhovThere should be more sincerity and heart in human relations, more silence and simplicity in our interactions. Be rude when you're angry, laugh when something is funny, and answer when you're asked.
