Nowadays, an increasing number of college students are doing part-time jobs. People hold different opinions on that. Some people think that there are many advantages for college students to have part-time jobs. Firstly, part-time jobs offer them opportunities to apply what they have learned in school and demonstrate their abilities. Secondly, it enables them to be more independent of their family and builds up their self-confidence. Thirdly, part-time experiences may be of great help to their future careers. Finally, part-time jobs can broaden their college lives and help them know more of themselves and society. However, some other people hold that doing part-time jobs has more disadvantages. The main job of college students is to study, not to work. If they have part-time jobs, they may have to reduce their time for sleep, rest, study and activities. Working several hours a day consumes a lot of time and energy and may affect their studies. As a result, they may find it hard to adjust to what the college expects of them as well as their employers expect, and finally, they may fall behind or fail in their studies. In my opinion, students can choose to take up a part-time job according to their own situation. The most important thing for them is to keep a good balance between part-time jobs and his study.
