I'm a person who has had a lot of different jobs over the years, selecting from fast-food, supermarket jobs, packaging at a hog processing plant, bartender, flagging on the highway, working on a pipeline with a bunch of men, inbound and outbound telemarketing, piano teacher, being a server, and teaching at elementary schools. None of the jobs listed above have lasted very long, but that's because of my lack of social skills. I'm hoping to change that with my upcoming teaching career.
I'll tell ya, the most nightmarish job for me would be to be a nurse or a doctor. They have to work insane hours and wipe people's butts and clean up puke and blood. Being a waitress is also difficult because you have to be on your feet all day and put up with peoples' complaints. Wouldn't be my cup of tea.
