“Gregg Easterbrook, author of “The Progress Paradox: How Life Gets Better While People Feel Worse,” [Random House, 2004] explains that “There are selfish reasons to behave in altruistic ways. Research shows that people who are grateful, optimistic and forgiving have better experiences with their lives, more happiness, fewer strokes, and higher incomes,” according to Easterbrook. “If it makes the world a better place at the same time, this is a real bonus,” he says.
Research shows that being grateful leads people into a higher state of happiness. Sonja Lyubomirsky author of The How of Happiness, [The Penguin Press, 2007] suggests that making a list of things people are grateful for in life, practicing random acts of kindness, forgiving enemies and appreciating life’s small pleasures leads to happiness.”
