Option #1: A Life-Changing Moment
Think of a specific experience that had a huge impact on you--something that really changed your life in some way (winning the state championship, riding your first roller coaster, surviving a car accident, going on your first date, etc.). Then, write a narrative about that experience. Make sure that it has an introduction, several body paragraphs, and a conclusion. Use time, dialogue, descriptive details, and one point-of-view to tell the story leading up to the climax of your life-changing moment. For instance, if your life-changing moment discusses your first date, the last body paragraph before the conclusion should detail your date and the previous body paragraphs should explain the events leading up to the date.
The conclusion should sum up the major subtopics in your story as well as explain how this event changed you. For instance, did it teach you a lesson? Did you walk away with a new appreciation for something?
