There's another way to lead a good life.

For years, we've been told the key to personal fulfillment lies in either happiness or meaning. But while they can provide comfort and security, the paradox of happiness and meaning is that the complacency they foster can make for an incomplete life, full of regrets, doubts and unanswered questions. So what's the alternative?

A psychologically rich life prioritises curiosity over contentment. Yes, doing something unusual, challenging oneself and learning something new can feel frustrating and unpleasant at times. But in Life in Three Dimensions, Shige Oishi weaves his own story with original research from fields ranging from moral philosophy, literature, culture, neuroscience, personality and psychology, to prove that psychological richness has benefits beyond happiness or meaning.

Ultimately, Oishi shows how anyone can use the three dimensions - happiness, meaning, and psychological richness - to build a fuller, more satisfying life.
