@feralgrad I agree that writing for yourself is incredibly important and that an MFA degree doesn't make someone a writer. I also agree that resilence is important in the success of a writer.
@Ydrl To answer your question, I can't say that I've swayed from writing fiction but I do read memoirs and CNF, especially when I'm doing research for a story. A few people in my life have suggested that I write a memoir but I'm not sure if I want to and would rather dedicate that time to something I'm passionate about. As others have said, it's okay to write different generes and even if you stay within one genre you can mess around with structure.
