Have you ever experienced joy from an act of kindness, helping others in need, or making a charitable contribution?

A Harvard Business School study (link below) suggests that giving to others is directly correlated with an increased sense of happiness. The Harvard researchers write: "Happier people give more and giving makes people happier, such that happiness and giving may operate in a positive feedback loop."
