It is common for students to find part-time job nowadays. Last summer vacation, I worked as a waiter at restaurant. It was the first time that I have earned money by myself. With the money I earned I could buy something what I needed. I was quite exciting about it. Now as a result of this part-time job, I needn’t to ask my parents for money as before. I think it helpful for a student to know about the outside world and that it’s a good preparation in the future. I not only understand the value of money, and also know how to get along with another. In a word, I had a fruitful vacation.
