May 5, 2026

From the bestselling author of The Happiness Advantage comes a bold new argument: the greatest predictor of your future is not your circumstances, your resources, or your résumé; it is the beliefs you hold about the world. Drawing on two decades of research and work with organizations ranging from NASA to Fortune 100 companies, Shawn Achor makes the case that beliefs do not simply reflect reality. They bend it.

The book highlights:

  • The Seven Core Beliefs: New research identifies seven specific beliefs that most powerfully predict future health, wealth, success, and education, and that can lift the cap on human potential.
  • The Great Drift: Achor traces the rise of what he calls the Four Horsemen of the Modern World, burnout, anxiety, loneliness, and depression, as evidence that destructive beliefs are quietly shaping outcomes at a societal scale.
  • Six Ways to Change a Belief: From rewiring how the brain processes experience to shifting language, social influences, and shared narratives, Achor offers research-tested strategies for transforming both personal and collective beliefs.
  • Beliefs Are Contagious: The book explores how individual belief shifts can ripple outward, influencing the people and communities around us in measurable ways.
