Somehow, I’m leery of a university degree that promises to make a creative writer of its students, especially one called Master of Fine Arts. Too much subjective work goes into it that cannot be taught. That is my opinion. You can learn from the masters/professors but you must also find that inner wellspring inside of yourself. At the same time, you need to train it and guide it into conventional language that will sell—if selling your work is your goal.
My best advice is to read the kind of work you want to write. Then read a hundred more books of that type. At the same time write, then write some more and rewrite till you lose count how many times you’ve written and rewritten. The single-minded goal is to write the best possible story you can. Have others read and comment.
It’s really hard work. It’s lonely work. And the feedback is drastically controversial and sometimes self-contradictory. The competition is fierce and getting published is no guarantee. Once you’re published, there’s no guarantee that your book will sell. If you want to get rich quick, writing’s not your ticket. You’re better off mopping floors or doing some other work such as collecting garbage that never runs out of style but nobody wants to do. I hear there’s good pay to be had.
Back to writing. If that’s really what you want to do, you’ll do it regardless of circumstances. You’ll find a way. Life can throw a temporary wrench into the mix but but you will always come back to it, MFA or not. And practice does help, if not make quite perfect.
EDIT: The details of your answer didn’t show at first. I’ve found informal writing groups very helpful. At the moment, I am on Scribophile, which is a learning experience. You may wish to check it out. Writers Digest is also very good.
