In many ways, there has never been a better time to be alive. Fewer among us are poor, fewer are hungry, fewer children are dying, and more men and women can read than ever before. How strange, then, to see such anger and great discontent in some of the world's richest nations. Why? A small hint comes from interesting research about how people thrive. In one ... experiment, researchers found that senior citizens who didn't feel useful to others were nearly three times as likely to die prematurely as those who did feel useful. This speaks to a broader human truth: We all need to be needed. Being needed" does not entail selfish pride or unhealthy attachment to the worldly esteem of others. Rather, it consists of a natural human hunger to serve. As the 13th-century Buddhist sages taught, "If one lights a fire for others, it will also brighten one's own way." Americans who prioritize doing good for others are almost twice as likely to say they are very happy about their lives. In Germany, people who seek to serve society are five times likelier to say they are very happy than those who do not view service as important. Selflessness and joy are intertwined. Everyone has something valuable to share. We should start each day by consciously asking ourselves, "What can I do today to appreciate the gifts that others offer me?" We need to make sure that global brotherhood and oneness with others are not just abstract ideas that we profess, but personal commitments that we mindfully put into practice.
