A poem, in all, can take anything from three months to two years to write. This one here, this messy old thing, took two years. I wasn't happy with it, so I tweaked it and I tweaked it and I tweaked it. I even had to hide it for a while because I was so angry about it. But then I got it back and I kept tweaking and now I'm really happy with it. But in the main, most poems take about three months. Even a really, really short poem, I'll tweak the words until they've got the right rhythm and the sound, and they say the things I want them to say. But everything you write always needs a little tweak. And anyway, I like tweaking because I like words.
