Maybe because I remember all to well what jobs I used to have:

- farm hand (heavy work on smaller less automated farms)

- construction (noisy, wet, dusty etc)

- security

- help desk

Being paid 8 hours a day to work on borderline interesting tasks, getting free lunch, being paid to study etc feels great. Oh, and I can work from home if I need to.

I also make my work interesting by putting some effort into it.
