The world isn't coming to an end, contrary to what you may have heard, says Jurriaan Kamp. Certainly there's upheaval and economic, political, and social instability, but the media's near-exclusive focus on conflict and disaster means that the progress and everyday acts of brilliance taking place across the globe go unnoticed, which contributes to the sense that apocalypse is at hand.

And pessimism can be fatal: Kamp cites research showing that those who indulge in negative thinking are more likely to smoke, be overweight, and have high blood pressure, high cholesterol, and an increased risk of Parkinson's disease than optimists. Meanwhile, evidence abounds that optimism—intelligent optimism, not a rose-colored-glasses brand of wishful thinking—is good not only for your mind but for your body, too.

Kamp demonstrates that, on the whole, we're living longer, becoming smarter, working less, and growing richer. Democracy is on the rise, and violence is declining. He explains how we can cultivate an outlook of informed optimism that will make our lives and the world better—because, as he quotes Helen Keller, “No pessimist ever discovered the secret of the stars, or sailed to an uncharted land, or opened a new doorway for the human spirit.”

Like many of us, Bob Miglani felt overwhelmed and anxious. He worried constantly about his job, his finances, and his family. It was a chance invitation to India, the land of his birth, that finally freed him. India, Miglani writes, is “the capital of chaos”: over a billion people living on one-third the space of the United States. And it was there that he learned to let go. The secret is to stop trying to control the chaos and focus on what you can control—your own actions, words, and thoughts. Move forward, make mistakes, trust your intuition, find your purpose. In this inspiring book, Miglani shares the experiences and encounters that helped him finally get it. What happens when you find yourself in an Indian village with no money and a plane to catch? How could an educated urban woman agree to a marriage after two dates? What keeps a rural health worker motivated despite the enormous need and such limited ability to help? What does trying to catch an insanely overcrowded bus teach you about perfection? Embracing the chaos, Miglani found, “leads us down paths we never would have walked on...It brings out strengths we never knew existed inside of us.”
