person? 

     A recent survey shows that in modern society, most people pick up practical goals, such as "earning

money to buy a house and a car" "to improve one's life quality" "finding a good job". Wang You worked

in a small firm (商行) in Nanjing. The job was good and he didn't have to work for extra hours. However,

he felt the work was not exciting at all and the life was boring. So he gave up his job and went to Beijing

in February, 2007. When he arrived in Beijing, he set his new goal as finding a good job.

progress and people's life goals have be- come more practical. One researcher says, "Everybody has

his/her own life goal, which will be surely different from people to people. If one is poor, one's life goal

will be to earn more money; if one doesn't have a diploma, studying hard to get a diploma will become

his life goal; and if one doesn't have love, his life goal will be to look for it. But if one has no life goal, he

will idle away (虚度) his lifetime."
