I sucked at economics. I did all kinds of things, because I thought someone had to do it. And I did not get paid. So, plenty of baby-sitting and voluntary stuff.
First paid thing was awesome though. Paid lousy, but did come with food, shelter and lots of mud. I was in an emergency excavation. A few years I went there for a couple of weeks. Pay? 75 guilder a week. Work, over forty hours. Experience? Awesome. And when it was hot, we'd start an hour early, and we'd end the day in the sea. Loved it.
After that, I got some receptionist telephonist jobs as a student.
