A person's happiness can be broad, or deep, or both, or neither. Broadness measures how multifaceted a form of happiness is. Financial success often creates quite broad happiness: it delivers a vast array of desirable objects, situations, relationships, and experiences. But does financial success deliver the broadest happiness possible? To investigate that, we have to look deep. Depth measures how "non-obvious" a form of happiness is. It's obvious to anyone that getting the situations and sensations they want will (often) bring them happiness. But it's not at all obvious that there's a way to be happy independent of situations and sensations. And it's even less obvious that in its fully mature form, achieving happiness independent of situations and sensations empowers a person to more effectively take control of situations and sensations. Optimal happiness is both deep and broad. Warren's book will point you in the right direction.
