During the school talent show, Lila played a piano piece she had practiced for months. She hit one wrong note near the end. Afterward, she refused to look at anyone and said, “I ruined it.” Her friend Mateo said, “I noticed the wrong note, but I also noticed you kept going—and the ending was beautiful.” At home, Lila listened to the recording. The mistake was there, but it was a small ripple in a steady river. The next day, Lila wrote in her journal: “One mistake doesn’t erase the whole performance.”
