I was a high school student then, from low-income family. So I had to support my family. My first job is to clean the table in a small restaurant. I still remember going there early and feeling anxiously about the new world. I worked hard but I was afraid of losing the job. At night, I was sometimes very tired that I didn't want to do our homework. I came to understand that it was difficulty to earn money, and that knowledge could change into my life. And what I learned from the job was much more important than the knowledge learning from school.
