Sara Solovitch grew up playing classical piano, a dedicated student and aspiring performer. But she quit at 19, undone by chronic jitters. Thirty years later, she decided to face her old fears, start over and brave the concert stage again. She tells the story in her new book, "Playing Scared: A History and Memoir of Stage Fright." Sara and I discussed the psychology of stage fright, its sufferers and treatments, how perfectionism and pressure set us up for failure, and the culture of classical performance.
