Recent studies in psychology suggest that the pursuit of self-interest may not be the
clearest path to the greater good or personal happiness, as so widely assumed. When
researchers study what makes us happy, they find that it is not personal wealth, the
strength of the stock market, inflation, or interest rates that cause the ebb and flow in our
personal well-being. What makes us happy, what matters in the end, is the quality of our
romantic and family bonds, our connection to our friends, and doing things for others.
