Study has been the necessary part of human's life. Many students take it as their duty and they don't realize the meaning of study. Most people believe that the purpose of study is to master some skills and make money. This is the basic function of education. I believe that the further meaning is to teach people the way of thinking. If there are two jobs, one is to sell pastry for 12 hours, and the other one is to work in the office for 8 hours, but the former can earn double income. The young people will surely take the second job, because they need more private time to do their own things. They have more things to chase besides making the ends meet.
