My advice is to understand that you don’t need an MFA to be a great writer. That said, getting an MFA is a wonderful thing! If you decide to pursue an MFA, you’ll get an automatic community of other burgeoning writers who will give you honest critiques of your works-in-progress, you’ll gain access to accomplished professors, and you’ll have uninterrupted time to focus on honing your craft. I would only caution that an MFA in no way guarantees you that your work will ever be published, nor does it necessarily provide access to a teaching job. It is, however, a wonderful luxury, and I advise you to savor every second of it.
