I've got a chance to step into a professor's shoes and teach college kids twice a week for the next two months. The salary and the hours are pretty meager - and I'd be giving up a short-term contract to do serious full-time work - but it seems like a great opportunity to try something I've always wanted. I'm not sure which I'd regret more: giving up the short-term contract (which is rare) in my chosen field, or turning down the opportunity to be a teacher. I'd still get to work, albeit irregularly, during the days I'm not teaching. I was all set to accept the offer until my sister warned me of the countless hours spent on mindless administrative work; on the other hand, the course modules and exams are all worked out in advance. Thoughts?
