What do you do? I teach English in a secondary (high) school, and a few hours in college.
More than one thing? I do not see where I could fit in a second job, what with being a mother of 2 (13 and 6 years old)! (Ellemeno: totally right you are, being a mum is much more difficult than most of the things you get paid to do!)
Work at home? You have no choice but at home as well when you are a teacher (very often at weekends and till the wee hours of the morning too...)
Seasonal work? FT, PT, variable, on call, hourly? Full time.
Are you doing what you wanted to do? When I started learning English at the age of 11, (on the first day I think), I came back home and broke it out to my parents: "Mum, dad, I want to teach English later". So yeah, I guess I'm doing what I wanted .
Would you prefer some other line of work? I'd love to be a writer (novelist or playwright). Can't find the time now, but maybe 'later'...
