This doesn't just apply to poets. It also applies to any writer who has been told "the rules". Rules can and will be broken in writing. What is in fashion today with certain publishers is out of fashion tomorrow. Write, write, write!!! Blaze that trail. Express your true self. Keep at it. Don't stop. There is a place for us all.
We keep looking and looking and looking for "the" answers. It's not necessary. You have already arrived.
