Happy Mind, Happy Life

10 Simple Ways to Feel Great Every Day




A brand-new edition of Dr Rangan Chatterjee's biggest book to date, reimagined with exclusive content and a beautiful new design

The Instant No.1 Bestseller

'Even your first taste of this book’s practical, inviting and effective strategies for happiness will make you glad you did.' - from the foreword by Oliver Burkeman, author of Four Thousand Weeks

Happiness is a practice, not a destination. We often treat happiness as something to pursue, a reward we’ll reach once life is finally in order. But what if happiness is not an outcome, but a practice - the foundation that shapes how we meet each moment?

Drawing on over twenty years as a doctor, Dr Rangan Chatterjee has seen that motivation and willpower rarely sustain us for long. True wellbeing only becomes possible when we learn to nurture what he calls core happiness - a steadier, more resilient form of joy that doesn’t depend on circumstances.

In Happy Mind, Happy Life, Dr Chatterjee blends science, case studies, and simple exercises to show how small, daily choices ripple into lasting change. Through ten simple but profound ways, you’ll explore how to:

  • Treat yourself with compassion and respect
  • Redesign your relationship with technology
  • Respond to criticism without being derailed

This is not a manual for quick fixes, but an invitation to reimagine how you live - so that health, clarity, and contentment flow naturally into your days.
