    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.

    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 I 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 that I should do a course and get a qualification(资格证书)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.
