Yup.
I work 50 to 60 hours a week at a farm/food store as their Advertising Manager/Creative Director.
I teach 6 hours a week at night at a local art college.
And I work about 10 to 20 hours a week doing freelance design work.
I do these many hours because my wife has been unemployed for over two years.
When she manages to land a new job (hopefully soon), I’ll probably do the same three jobs, just a lot less hours.
