Money is life energy

Robin and Dominguez argue that money is something we trade our life energy for: the limited hours of our lives. Seeing money this way changes the question from what something costs in dollars to what it costs in time.

They also describe a fulfilment curve. Spending on survival and comforts brings more fulfilment, up to a peak they call enough. Beyond that point, more spending and more stuff bring less satisfaction, not more. The book’s nine-step programme is designed to help readers find their enough.
