Embrace the transformative power of variety and experience for a life of fulfilment. We’ve been told that a good life is a stable life, a comfortable or purposeful life that follows a well-trodden path. But is a happy life, with the complacency it fosters, or even a meaningful life, which comes with narrowness and misplaced loyalty, the only path to a good life? In Life in Three Dimensions, one of our foremost psychologists Shige Oishi proposes a third dimension to a good life: psychological richness, a concept that prioritizes curiosity, exploration and a variety of experiences that help us grow as people. Weaving his own story with original research from fields ranging from moral philosophy, literature, culture, neuroscience, personality and psychology, Oishi proves that psychological richness has benefits beyond happiness or meaning. Ultimately, we see how anyone can use the three dimensions - happiness, meaning and psychological richness - to build a fuller, more satisfying life with fewer regrets.
