It's simple, just post what you do to make money.
Right now I'm a high school student, but I work part-time as an admissions monitor at my high school's pool. Basically I collect money from swimmers, and that's about it. It's probably the easiest job I'll ever have, and considering I make $9.25 an hour for doing almost nothing, I don't think I'm going to quit until I go to college. The only downside is that every other weekday I have to wake up at 5:30 to go to work, which really sucks. On top of that, I have to stand in the freezing weather for about 30 minutes in order to open the gate to let swimmers in. But all in all, it's a great job.
