Janitorial helper at my high school, though it was more of a moving job, as we were also moving all the stuff to the newly constructed building.
It was actually a decently fun job TBH. Getting to see my new school before everyone else and knowing the building was kinda cool too at the time, and seeing things progress did have some form of satisfaction and at the end it was crazy to look at all those desks and chairs and other items and say "we moved all that!". I did that job the summers after as well, minus all the moving, was very laid back.
I was getting minimum wage, which was 7.15 at the time, but it was enough for me to build myself a new computer every year, and save the rest for college. I only worked in the summer while I was in school and college, and had enough money.
So I worked that for a few summers, and then my 2nd job was a server tech for a couple summers until I graduated. Then my permanent job, I went to work at helpdesk for the same company, and now I'm a server tech, go figure. I'd have to say things worked out pretty nicely for me.
