Amy advises the reader to consider how holding onto guilt serves them and the world, and emphasizes that forgiving oneself does not mean condoning the actions. She encourages the reader to acknowledge their mistake, learn from it, and move forward, as they have not repeated the behavior in the past 20 years.
