Happiness, rather than working hard, is the key to success, according to research published yesterday．Cheerfu1 peop1e are more 1ikely to try new things and challenge（wk战） themselves， which strengthens their good emotion and leads to success in work，good relationships and strong health，say psychologists（心理学家）．
The findings suggest that happiness is not a “ feel-good” luxury（奢侈品），but is necessary for people’s well-being．What is more, happiness can also reach an entire nation，with people in” happy” nations being more likely to help others．
The link between happiness and success was studied by a team from the University of California Riverside，led by Professor Sonja Lyubomirsky．
First, they examined questionnaires that ask peop1e about their 1ives．“ For example, they show that happy people are likely to earn higher incomes” said Lyubomirsky．Having established the link，they wanted to discover the cause．
“Almost always it has been taken for granted that things that connect closely to happiness are the causes of happiness，but it could be just the opposite that those things are likely to be caused by happiness，” said Professor Ed Diener from the University of Illinois，another author on the paper．
“ There was strong evidence that happiness leads people to be more sociable，more generous and more productive at work，to make more money，and to have stronger immune（免疫）systems，”said Lyubomirsky．
The research shows that while success can put a spring in someone’s step，peop1e need happiness in the first place to achieve success．
According to the study， around 4 out of 5 people in modern industrialized nations arc happy at any one time．
Success was not just about earning lots of money．“ We describe success as having the things that culture or society values，whether it be friends，close family, money and income，or long life，”said Diener．
However，sorrowful people arc not predetermined to lead a life of failure．
