     I really love my job because I enjoy working with small children and like the challenges and awards from

the job. I also think my work is important. There was a time when I thought I would never have that sort of

career (职业).

     I wasn't an excellent student because I didn't do much schoolwork. In my final term I started thinking

what I might do and found I didn't have much to offer. I just accepted that l wasn't the type to have a career.

     I then found myself a job, looking after two little girls. It wasn't too bad at first. But the problems began

when I agreed to live in, so that I would be there if my boss had to go out for business in the evening. We

agreed that if I had to work extra hours one week, she'd give me time off the next. But unfortunately, it didn't

often work out. I was getting extremely tired and fed up, because I had too many late nights and early mornings

with the children.

     One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told

her about my situation. She suggested me that I should do a course and meet a qualification if I wanted to

work with children I didn't think I would be accepted because I didn't take many exams in school.

     She persuaded me to phone the local college and they were really helpful. My experience counted for a lot

and I got on a part-time course. I had to leave my job with the family and got work helping out at a kindergarten.

     Now I've got a full-time job there. I shall always be thankful to Megan. I wish I had known earlier that you

could have a career, even if you aren't top of the class at school.
