Another theme could be the pursuit of dreams. Maybe Michael has a passion for art, but he has to make choices that either support or hinder his dream of becoming an artist. He might have to choose between taking art classes and other academic requirements. Or perhaps he has to decide whether to enter an art competition, which could be a big step in achieving his dream. These choices related to his dreams could be a central theme in the story, showing how high school is a time when students start to figure out what they really want to do in life.
