I had a good time delivering pizzas in uni. The work is simple but there's just enough variety in destinations so it's not boring. The pay is shit though.

I used to be a bicycle messenger as a student, and I liked it very much. Pay was low, and both companies I worked for finally went bankrupt (not due to my service though).

In my youth, I wanted to become a physiotherapist. But when I worked as an assistant nurse during compulsory community service (as alternative to military service, so I did not have to join the army), my colleagues told me to go to uni instead and do something intellectual.
