My First Job
I was six when I joined my father and two elder brothers at sunrise in the fields of Eufaula. Okla.  36  the time I was eight I was helping Dad fix up old furniture. He gave me a cent for every nail I  37  out of old boards.
I got my first  38  job, at JM’s Restaurant in town, when I was 12. My main responsibilities (职责) were  39  tables and washing dishes,  40  sometimes I helped cook.
Every day after school I would  41  to JM’s and work until ten. Even on Saturdays I  42  from two until eleven. At that age it was difficult going to work and  43  my friends run off to swim or play. I didn’t necessarily like work, but I loved what working
  44  me to have. Because of my  45  I was always the one buying when my friends and I went to the local Taste Freeze. This made me  46  .
Word that I was trustworthy and hard-working  47  around town. A local clothing store offered me credit (赊帐)  48  I was only in seventh grade. I immediately  49  a $68 sports coat and a $22 pair of shoes. I was  50  only 65 cents an hour, and I already owed(欠) the storekeeper $90! So I learned  51  the danger of easy credit. I paid it  52  as soon as I could.
My first job taught me self-control, responsibility and brought me a  53  of personal satisfaction few of my friends had experienced. As my father,  54  worked three jobs, once told me, “If you  55  sacrifice (奉献) and responsibility, there are not many things in life you can’t have.”How right he was.
