It can be very effective to show that a hero is unable to perform some simple task at the beginning of the story. In Ordinary People the young hero Conrad is unable to eat French toast his mother has prepared for him. It signifies, in symbolic language, his inability to accept being loved and cared for, because of the terrible guilt he bears over the accidental death of his brother. It’s only after he undertakes an emotional hero’s journey, and relives and processes the death through therapy, that he is able to accept love.
