     Just 25 years ago, the top three career hopes for young people in Britain were teacher, banker and doctor.

Now, they want to be sports star, pop star and actor, according to a survey by the Guardian newspaper.

     Rachel, a character in the popular TV show Glee, may be said to speak for British teenagers. "Nowadays

being nobody is worse than being poor." he said.

     Emma Brockes, a reporter with the Guardian, believes it is "the bad influence of celebrity (名人) culture"

that is to blame. "When children wanted to be doctor, it wasn't because they were really more interested in the

functions of human organs than they are now; you go where the respect is." she wrote.

     It could explain why there has been such an increase in levels of anxiety and depression Dr Carlo Stranger,

of Tel Aviv University, studied the sense of self for his new book The Fear of Insigni ficance: Searching for

Meaning in the 21st Century. He told the Daily Mail that young people now are "affected by the close

connection to the global entertainment network, which has turned ranking and rating people according to wealth

and celebrity into an obsession (痴迷)."

     "As humans, we naturally measure ourselves to those around us, but now we live in a global village. We are

comparing ourselves with the most 'important' people in the world and finding ourselves wanting," he said

Today, even high achievers constantly fear that they are insignificant when they compare themselves to success

stories in the media.

     The way out? Simply stop measuring your achievement through a fantasy of wealth and celebrity. Dr.

Strenger said that it is a process called "active self-acceptance through a constant search for self-knowledge

through life".

     "The fear of insignificance can only be overcome through strong individual and cultural identity over and

above measurable achievement," he said.
