     WHAT can help you make a fortune in the future? Graduating from a top university might not be enough.

A new study from the University of Essex in Britain has shown that the more friends you have in school, the

more money you'll earn later.

     The idea that popularity could have a serious influence on one's earning potential shouldn't come as too

much of a surprise. The researchers noted that if you want to get ahead in life, social skills and networking

are easily as powerful as talent and hard work.

     "If a person has lots of friends, it means that he or she has the Ability to get along with others in all kinds

of different situations," said Xu Yanchun, 17, from Nantou High School in Shenzhen, who totally agreed with

the recent finding. "Also, friends always help each other. They not only create wider social circles for you but

lift your mood when you are occasionally in low spirits." said Xu. She believed that all this helps you "earn a

higher salary".

     Maybe that's why some people think the younger generations are in the age of Friendaholism (交友狂症)?

A woman even complained that the networking website Facebook's 5, 000-friend limit was too low for her

large reserve of social contacts.

     But what does a friend mean? Should friends be regarded as a form of currency?

     "Call me uncool, but I think of a friend as an actual person with whom I have an actual history and whom

I enjoy actually seeing. It seems, however, that this is no longer the definition of a friend," said Meghan Daum,

who works with the Los Angeles Times in the US.

     Daum dislikes the idea that quantity trumps quality in the age of Friendaholism. She thought the idea of

friendship, at least among the growing population of Internet social networkers, was to get as many of not-

really-friends as possible. For example, a friend might be someone you might know personally but who could

just as easily be the friend of a friend of some other Facebook friend you don't actually know. Although she

agreed that social ties grease (润滑) the wheels of life, she also wamed, "Too bad one thing money can't buy

is a real friend."
