Dr. Robert A Emmons is a scientific expert on gratitude. He is a professor of psychology at the University of California, David, the founding editor-in-chief of the Journal of Positive Psychology, and author of two books on gratitude. His extensive research on the psychology of gratitude and its impact on individuals show that those who regularly express gratitude increase their "happiness" by 25%. They are also more optimistic, sleep better and have more energy. Other researchers such as Dr. Michael E. McCullough, University of Main and Dr. Martin E.P. Seligman, University of Pennsylvania also found that those who regularly express gratitude increased their happiness, improved their relationships with others and resulted in fewer trips to physicians.
These studies don't necessarily prove cause and effect, but there appears to be enough scientific evidence to show a positive relationship between gratitude and one's self worth and well being.
All of us can develop a sense of gratitude. It is not an emotion that is necessarily innate. It is learned. That's why our mothers, fathers and others teach us when and how to express it. If expressing gratitude is not your long suit consider these activities which contribute to an attitude of gratitude.
