The document discusses a story about a peasant girl named Nell who finds a magical book that teaches her about the world. Unlike rich girls who received the same book, Nell uses the knowledge from the book to change the course of history. The key difference was that Nell had more opportunity and motivation to create impact due to her circumstances, whereas the rich girls were focused more on approval. The document urges the reader to measure their impact, not candy (approval/grades), and to pursue ambitious goals that create real change.
