<human>: I'm looking for advice on what sort of job to transition to when my most recent work experience has been teaching college-level introductory English courses. 

After around two years of teaching, I've decided that teaching college English really isn't for me. As the semesters go by, I understand more and more that the sort of classes that I'm permitted to teach are the sort of classes I would have HATED as a student. And teaching them is like taking those classes all over again, only with 25 times the homework and the obligation to perform for the whole class. Don't even get me started on dealing with students just out of high school who come to college already broken as the result of a broken system...or the lack of departmental support or oversight...or a thousand other things.

I'd suck it up if it were likely for me to have a decent chance at a full time position, but it's not even that likely that I can find a full-time position teaching, since most of the classes that I am able to teach are given to graduate students and part-time faculty--the best I can hope for if I stay on course the next 3 years is to keep working part time at two different colleges doing a job I despise. 

The rub is, a lot of the jobs that I'm prima facie qualified for--for example a position as a librarian or as an ESL teacher-- seem to require an additional certification or SLIGHTLY different degree or emphasis. My question then becomes, what general fields are actually more forgiving in terms of requiring certifications?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: For what type of jobs does being a college-level English instructor make me competitive? And any advice on how I should frame the transition in a cover letter or resume?
