     “When I grow up, I want to be...”

        Almost all of us have thought about, or been asked to think about, our future careers. Our answers may differ greatly. Even now your aspirations may have changed from when you were in primary school.

        However, it seems career options aren't only based on personal taste. In a survey carried out by teens, doctors, lawyers, and bankers were some of most popular careers that people said they hoped to follow. This is in line with a similar survey carried out in the U.K. in May 2011 by job website monster.co.uk, in which medicine was the top choice among U.K. teenagers aged between 13 and 17.

        Medicine and law are two of the oldest and best known professions. Their prestige (威望) may come from the fact that doctors and lawyers are some of the most esteemed members of society, and they make good money. Joining these high­profile professions is often seen as a sign of upward social mobility.

        It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators of a successful career. British young men list the U.K. tycoon Alan Sugar, Microsoft founder Bill Gates and Facebook chief Mark Zuckerberg as their top role models “for their wealth”. Just as Chinese teenagers see being a banker as a good and fun pathway to “wealth”.

        However, not every child has the makings of doctor, lawyer, or banker. They are those who see fulfillment and happiness in other areas, and many teenagers dare to ink more individuality into their career options. As the Teens' survey discovered, a variety of unconventional jobs—coffee shop owner, gourmet (美食家), waiter at a fast food restaurant—are among teenagers' career choices. They can be equally interesting and rewarding jobs.

       With every choice comes responsibility and challenge, and all career paths require specific education and training, you have to learn to balance optimism and confidence with being realistic about your particular talents and skills.
