How can we live a good life? It’s a question psychologist Dacher Keltner has spent much of his professional career trying to answer. In his latest book, Awe: The New Science of Everyday Wonder and How It Can Transform Your Life, he argues that an appreciation of the world — whether through experiencing the natural beauty of Yosemite National Park or simply being with a friend — not only benefits us mentally and emotionally but is a crucial part of our physiological health. A big part of well-being, he says, comes from what primatologist Jane Goodall calls “being amazed at things outside yourself.” And his studies show this is a skill we can cultivate.
