Mirriam Websters online dictionary defines happy as: enjoying good health and satisfaction. Sounds nice, doesn’t it? I know a secret that can lead to happiness. Now you may ask, what secret is that? It’s a well-known secret, in fact. Perform a random(随意的) act of kindness per day.
Positive psychology is the scientific study of the strengths and virtues that enable individuals and munities to grow. According to University of Pennsylvania’s website, positive psychology has three central concerns: positive emotions, positive individual character, and positive systems. Understanding positive emotion includes the study of satisfaction with the past, happiness at present, and hope for the future. Understanding positive individual character consists of the study of the strengths and virtues, such as love, courage, creativity, curiosity, self-knowledge, self-control, and wisdom. Understanding positive systems needs the study of meaning and purpose as well as the strengths that help the growth of better munities, such as responsibility, leadership, teamwork, purpose, and tolerance(忍耐力).
Positive psychology focuses on strengths as well as weaknesses, on building the best things in life as well as repairing the worst. It asserts(断言) that human goodness and excellence is just as real as sadness and illness, and that life consists more than seeking the answers to problems. All these things can be summed up in one concept: giving can equal a meaningful life, i.e. happiness.
But you are probably wondering how. Well, let’s examine the research, shall we? A 1996 study showed that wealth is only weakly related to happiness both within and across nations, particularly when ine is above the poverty level. So money does not mean happiness. In 2000, a different study showed that activities that make people happy in some way—such as shopping, good food and making money—do not lead to satisfaction in the long term, indicating that these have quick diminishing returns(收益递减).
However, on the other hand, we also know that people who witness others perform good deeds experience an emotion which drives them to perform their own good deeds. Making a contribution to the lives of other people may help to extend our own lives.
This is why I make a point of trying to do something nice every day. Sometimes I tip much larger than I need to. Sometimes I just smile at someone who looks like they really need it. A random act of kindness is an act that receives just as much as it gives. You’ll be happier. They’ll be happier. And you’ll live longer. So, please, perform a random act of kindness each day.
