Description Learning which thoughts lead to good outcomes is powerful, but it starts by learning that we do get to choose those thoughts. Worry guides readers through some examples of times when readers may feel worried and show just how Bubble and Slug guide each protagonist through their dilemmas. Each scenario asks the reader to choose between Bubble and Slug and ultimately determine how each story ends. Using techniques author Gail Hayes has developed through her work as a counselor, Worry gives the reader a chance to explore the choices we make daily and learn about their impact.
