A trouble with poetry is the presence of presumptuousness in poetry, the sense you get in a poem that the poet takes for granted an interest on the reader's part in the poet's autobiographical life, in the poet's memories, problems, difficulties and even minor perceptions. I try to presume that no one is interested in me. And I think experience bears that out. No one's interested in the experiences of a stranger - let's put it that way. And then you have difficulty combined with presumptuousness, which is the most dire trouble with poetry.
Billy CollinsI think what gets a poem going is an initiating line. Sometimes a first line will occur, and it goes nowhere; but other times - and this, I think, is a sense you develop - I can tell that the line wants to continue. If it does, I can feel a sense of momentum - the poem finds a reason for continuing.
