Hour 1: When Misty Copeland first dreamed of becoming a ballerina, she was a 13-year-old girl living in a rundown motel with her five siblings. But that didn’t keep her from rising through the ranks to become a soloist with American Ballet Theatre. We’ll talk to her this hour about how she accomplished her dream, which she writes about in her new memoir, Life in Motion: An Unlikely Ballerina (Touchstone). Copeland is in town for an appearance tonight at the Dallas Museum of Art for Arts & Letters Live.
