I think the main thing my MFA did for me is help establish connections to other writers and academics. It did also strengthen my writing, especially through the workshops and crafting my thesis.
I work in higher Ed now, mainly in Student Affairs. I got the job by working there while getting my MFA, and I teach first year writing because of the connections I made while in the program. So, somewhat a related field!
Happy to chat more if you’re considering an MFA and/or have specific questions.
