Meet Harvard Professor Arthur Brooks, whose collaboration with Oprah, a book called Build the Life You Want, focuses on the science and research behind happiness. In this conversation, Paula and Arthur discuss a range of topics, including metacognition (thinking about how to think), the neurobiological basis of ruminating, and how to balance the concept of contentment with the innately human urge for ambition and progress. Arthur also offers a formula for happiness: enjoyment + satisfaction + meaning and purpose. Listen to the episode to learn more.
