My first job was babysitting. I started when I was 12 and babysat many nights a week, weekend days and during the summer all through high school and a bit in college. I loved being with the kids, and I would tutor them, too, if they needed the help. I babysat over 300 kids, from 4 weeks old to 13 years old.
My mother was always trying to get me to take a "real" job, because babysitting paid much less than minimum wage. At one point, she set up an appointment for me at my high school's vocational office. The vocational counselor asked me what kind of work I liked, and I told him I loved babysitting, and he said, "That isn't what your mother had in mind, but I could use a good babysitter" so I ended up babysitting for his kids. To his credit, he did arrange a job interview for me at a local cleaners, but the guy asked me why I wanted to work at a cleaners, other than to earn money, and I couldn't think of anything to say. I didn't get that job!
My mother found my first "real" job for me, at an Italian food warehouse. They supplied all the Italian restaurants in the area, and they had a little market for the neighborhood people. My job included stocking shelves, cutting meats and cheeses in the deli, and sweeping up. It was a two-week temporary job, as they needed someone just until the owner's neice got home from college. My mother was convinced that if I did a good enough job, I could win it out from under the neice. I don't think so! I did a decent job, but I wasn't that excited about the work. It was a nice first job, but two weeks was quite enough.
