Do you have a goal for life? What's it? Do you want to become a writer, singer or just become a rich 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.

Nowadays more and more people want to live a better life. This fact shows that the society is making progress and people's life goals have become 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. {007}”
