Sometimes poems appear like rare butterflies; you have to swiftly capture them or they fly away again. A poet friend of mine has been known – in the absence of a notebook – to ‘catch’ a poem on the back of a cornflake packet. I am lucky to have had this experience myself; an idea comes into my head and flows via the pen or keyboard into a first draft of a poem on the page. It is hard not be pleased with yourself when you create something that didn’t exist before – especially if it contains an original idea. First drafts are often the most fun to write, with the highest reward-to-effort ratio. But then comes revision.
