And treating poetry as a performing art emphasizes its ephemerality. A printed poem can be endlessly reprinted, photocopied, scanned, uploaded, cut and pasted - but a performance, even if somebody's there with a video camera, is one time only: the audience experiences something that won't exist when the performance is over, and which won't ever be reproduced in exactly the same form. I find that appealing.

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.

Poetry isn't an efficient tool for preserving experience, any more than it's an efficient mode of communication, but who says that it should be efficient?

When I started reciting my own poems in public, I worried that it would seem too theatrical, but now I find recitation very natural, because it allows me to address audiences directly.

I try not to think in terms of what poems or poets should do. Most of us appreciate a wide diversity in music, in cooking, in movies, but in our own medium, poetry, we often fail to make allowances for tastes and projects other than our own.

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.

I like poems that immediately claim my attention, instead of taking my attention for granted. At first read, I want to feel compelled to pick up the poem again; I want to be curious about its byways and secret corners.
