Natasha Trethewey was once a creative writing teacher at Auburn University. I took a class from her, my only undergrad poetry writing class. I'm not a terrible fiction writer, but I am likely one of the worst poets. She was a patient teacher and very much lived out this quote in our class:
Well, I've written bad poems myself, so I'm sympathetic. There are those of us for whom it is necessary to write poetry. And if you are dedicated to that and willing to work very hard, your poems will get better. I have to believe that.
