A certain amount of time on one's own I think is important. It could be somewhere where there's other people, like a train, as long as there's nobody you know wants to talk to you. I don't listen to music or anything when I'm writing because if I've got music on I listen to it - I can't concentrate on my work. I'm always very surprised when I hear about people listening to music while they write. If I haven't written anything for a while and I want to get myself going there are two things: one is reading some poems, and the other is writing anything, writing my diary or writing anything and if I do those two things for a bit usually some idea for a poem will come up.
