Writing poetry was a great way to find out about poets. I get inspired by reading other works and I think I learn that way too. Right now I'm trying to write a play and I'm finding some excellent playwrights and plays. I loved Mamet and rereading and reading new stuff by him. Martin Mcdonagh is fantastic and so is Tracy Letts.
I am finding some common themes in plays. Madness seem to be a good item to toss into a play. An unlike film, a downbeat ending appears to be the way to go.
