I was a high school student then, from low-income family. So I have to work to support my family. My first one job was to clean tables in a small restaurant. I still remember going there early and felt anxious about the new world. I worked harder because I was afraid of losing the job. At night, I was sometimes very tired to do my homework. And I came to understand that was not easy to earn money, and knowledge could change my life. So I learned from the job, in a hard way, was much more important as what I earned.
