Usually the poems are written in one sitting. There's always a groping towards some satisfying ending. But I'd say the hardest part is not writing. Once the writing starts, it's too pleasurable to think of it as a difficulty.
Billy CollinsThe literary world is so full of pretension, and there's such an enormous gap between how seriously poets take themselves and how widely they're ignored by everybody else.
Billy CollinsThere's this pet phrase about writing that is bandied around particularly in workshops about "finding your own voice as a poet", which I suppose means that you come out from under the direct influence of other poets and have perhaps found a way to combine those influences so that it appears to be your own voice. But I think you could also put it a different way. You, quote, find your voice, unquote, when you are able to invent this one character who resembles you, obviously, and probably is more like you than anyone else on earth, but is not the equivalent to you.
