A、One can benefit a lot from working with his father. B、Manual laborers shouldn’t be looked down upon. C、One should always do hi

My father woke me up early one morning when I was fourteen, and announced "Get up! You are going with me to cut grass." [23]I felt proud and excited, because my father thought I was responsible enough to help him in his business. Still, that first day was very hard. From sunrise to sunset, my father, my younger brother and I cut and trimmed very large yards in a well-to-do part of the city. By the end of the day, I was exhausted, but I felt good. I had put in a hard day’s labor and had earned six dollars. One day, my father spotted some leaves I had missed cutting, and pulled me aside.
     [24] "Cut that section again," he said firmly, "and don’t make me have to tell you to do it again." The message was clear. Today, [25]I stress the importance of doing a job right the first time. Every job I have held, from cutting lawns to washing dishes to working a machine on the construction site, I have learned something that helps me in my next job. If you work hard enough, you can learn from any job you do.
