“Be proud of what you do whether you are a boss or a cleaner.” my father always told me. When I was 18, I got a summer job in a hospital. I was told that my job would include sweeping floors. I smiled and remembered Dad’s words.

Even though my job was the lowest, it made me feel excited. I thought it was a challenge because it was my first job. I learned to be on time and tried to do everything well. As a result, I was respected（尊敬） by doctors, nurses and patients. Each morning I imagined that the dirty dishes would make patients sicker if I didn’t wash them clean. After breakfast was done, I started sweeping the floors of all patients’ rooms and cleaning toilets. Though I was tired, I wanted to do the job well. People would say, “That young boy really does a good job.” That gave me a pride.

Working in the hospital taught me that being proud of one’s job was important. It doesn’t matter whether the job is sweeping floors or managing a large business. Whatever I have done, my father’s words have always stayed with me. I have swept floors, and I have been a manager. I think Dad would be proud of me.
