Life in Three Dimensions:

How Curiosity, Exploration, and Experience Make a Fuller, Better Life

Abstract: Shigehiro Oishi’s father has lived his entire life in a small mountain town in Japan. But as a young man Oishi felt compelled to follow a winding road that led him far from home. He became an award-winning psychology professor, seeking to know which path—to stay or to go, the familiar or the unknown, his father’s path or his own—is the better path to a good life. In Life in Three Dimensions, Oishi shares his journey of discovery and offers readers a groundbreaking new understanding of happiness.

What makes for a good life, he asks? Is it the simple, predictable pleasures we call happiness? Or can happiness lead to complacency and regret? Is the answer a deep sense of meaning and purpose? Or can a life of purpose invite narrow or misplaced loyalties? Both happiness and meaning as paths to a good life have decades of scientific research to support them. But in recent years, Oishi has uncovered a third dimension to a good life, psychological richness. A psychologically rich life prioritizes curiosity, exploration, and a variety of experiences. These can be as simple as taking a walk, as complex as moving to a new country. Key to a psychologically rich experience is a shift in perspective that helps us grow.
