`This book has the power to change everything' Susan Cain `A completely original treatment of a completely new and original idea' Arianna Huffington A ground-breaking exploration that turns everything we think we know about happiness on its head Have you ever wondered why we stop to watch the orange glow of a sunset or flock to see cherry blossoms in the spring? We are often made to feel that the physical world has little or no impact on our inner joy. Increasingly, experts urge us to find balance and calm by looking inward - through mindfulness or meditation - and muting the outside world. But what if the natural vibrancy of our surroundings is actually our most renewable and easily accessible source of joy? In Joyful, designer Ingrid Fetell Lee, whose TED talk has been viewed over 1 million times, explores how the seemingly mundane spaces and objects we interact with every day have surprising and powerful effects on our mood. Drawing on insights from neuroscience and psychology, as well as design, she explains why one setting makes us feel anxious or competitive while another fosters delight and sharing - and, most important, she reveals how we can harness the power of our surroundings to live fuller, healthier and truly joyful lives.
