Others might disagree with me, but I currently work in higher education and while my colleagues all have advanced degrees, they are from a variety of disciplines (MFA in creative writing, PhD in Music Conducting, MA in Cultural Studies etc.). I think it might be worth applying to positions in higher education this upcoming year to see how much success you have. If you get an entry-level position and cannot advance, perhaps you can simply enroll in an HESA degree at the college you work at. I would also suggest you look up the backgrounds of those in positions you aspire to.
