I've been struggling with creating a bio for 
Rattle, who accepted my poem in November and is getting quite antsy to receive it.  (whines) But it's hard!  They didn't want a traditional bio, but something more about why I write.  So I finally came up with this:
I have been a writer since kindergarten, when I wrote illustrated tales of shapeless purple monsters eating everyone and then crying.  My themes haven’t changed  much since then.  I came to poetry after writing fiction for many years – I eventually came to dislike the awkwardness of “plots” and how false they seemed.  Poetry seems to claim a lot less than fiction, and question more and in a way, leave more space in the universe.  I read once in a Zen magazine that poetry is about “the space around it” – the white page between line breaks, the gap between the poem and the bottom of the page – and I think my writing tries to make peace with the space, use it in a way that gives the reader an opportunity to pause and make their own way, whatever that means.
