Neuroscience reveals that happiness is not just a fleeting emotion, but a measurable brain state grounded in the brain's reward system and shaped by its social, cognitive, and aversive networks. Complementing these insights, psychology helps us understand which life goals are worth pursuing, which social connections most enrich our well-being, which self-help practices foster a positive mindset, and how to effectively manage the key obstacles to sustained happiness-stress, fear, and depression.

If Only Happiness Was a No-Brainer integrates findings from neuroscience and psychology to present five essential pillars of happiness: pleasure, purpose, people, perspective, and resilience. Through lighthearted personal stories and clear, evidence-based insights, this book shows how each pillar is expressed in the brain-offering readers an understanding of how to have a more meaningful, connected, and happy lives.
