Michelle Gielan was drawn to the science of happiness when she quit a dream job. As an anchor of two national news programs for CBS News, she was disturbed by the amount of negativity in her reporting. So she left to study positive psychology—the science of happiness and human potential—under Dr. Martin Seligman at the University of Pennsylvania. Today, she’s a leading expert herself, and a best-selling author. She studies the power of mindset to create happiness and forward progress in our lives.
