Recently, in the hope of earning both money and social experience, I became a door-to-door salesman. I once read a saying: "If somebody wants something of you, you will be treated as warmly as spring, but if they don't you may be treated as coldly as winter." You may consider it an exaggeration(夸张),but if you are a salesman, it is clearly correct.
You would never have found it to be so true if you hadn't been a salesman. You needn't stand doubtful looks and unfriendly views; you needn't listen to something completely wrong and nod to say that it was quite right; you needn't always keep patience and smile; you needn't repeat the same sentences over again; you needn't talk to somebody you dislike.
I did this work for a month; then I decided to give it up. In spite of the above reasons, I found I was paying too much attention to the job and thus sacrificing my study time. The latest test result proved that my grades were getting lower. Even worse, I hadn't enough time to join my classmates in college activities. Sometimes I felt lonely and unhappy because of both my study and my part-time job. Now I don't think it is worth doing such a thing even though I was earning money at great cost.
Newspapers and magazines often publish stories about good students who do part-time work and keep high scores in class. But according to my experience, part-time work can have some strong bad effects on study.
Most students don't see the relationship between studies and work in a correct way. In my opinion, if it isn't a must for money reasons, students should be cautious about taking up a part-time job. In western countries even the children of very rich families take part in hard jobs during the summer vacation.
