Start listening to what you say. Are your comments and ideas negative? You aren't going become positive if you always say negative things. Do you hear yourself say"I could never do that","I never have any luck","I never get things right". Wow - that's negative self-talk! Try saying"I am going to do that","I am so lucky""I always try to get things right". Can you hear how much better that sounds?

I want each poem to be ambiguous enough that its meaning can shift, depending on the reader's own frame of reference, and depending on the reader's mood. That's why negative capability matters; if the poet stops short of fully controlling each poem's meaning, the reader can make the poem his or her own.

I think that being mindful of your own biases tends to lead you into ambiguity, not clarity, and that following those ambiguities is the only way to approach the universal.

My dad, a mathematician, raised me to believe that mathematics is beautiful, so math is a part of my imaginative terrain. In my late 20s I wrote several 11-line poems because I wanted to create poems that couldn't be uniformly divided into couplets, tercets, or quatrains, 11 being a prime number.

I believe strongly in what John Keats called negative capability: the trait or practice that allows a poet to remain in uncertainties, mysteries, doubts, without any irritable reaching after fact & reason. For Keats, William Shakespeare exemplified negative capability, and I do think it's extraordinary that for all the thousands of pages Shakespeare left behind, we really don't know much about Shakespeare's own personality or opinions.

I wrote the poems in Charms Against Lightning one by one, over almost a decade, and I did not write them toward any theme or narrative. But once I really got serious about putting together a book, I began to see that in fact there were themes across the poems, if only because my own obsessions had brought me back time and again to the same ground. I realized that any ordering of the poems would determine how those themes developed over the manuscript, and how the collection's dramatic conflicts were resolved.

I don't think I'd ever get any better as a poet if I didn't push myself, very deliberately, to grow. My best poems surprise me, as they should, but I fight them at every turn, possibly just because I'm stubborn.
