Finding a title for a book is something that I work really hard at ... So, in Salt, I realized that the book was a lot about how people live on the earth together and who has access to the resources of the earth. So salt was a very specific thing that people needed, but it's also symbolic because of the way it comes out of the earth.

If I have some extra words and I'm trying to make it fit into that shape, then I just sort of take out the extra words, almost like a sculptor would take a piece of granite. It's almost like cutting out the words that aren't needed in order to make it a stronger poem and still say exactly what I want it to say.

I think of everything that I want to say and then I think of the way that I can say it most precisely. And this has to do with poetry too, to me, that poetry helps me focus on the details of language.
