"Civilisation's greatest single invention is the sentence. In it, we can say anything. That saying, however, is difficult and peculiarly painful. Whether we are writing a novel or a letter to our bank manager, we have the eerie sensation that we are not so much writing as being written, that language in its insidious way is using us as a medium of expression and not vice versa. The struggle of writing is fraught with a specialised form of anguish, the anguish of knowing one will never get it right, that one will always fail, and that all one can hope to do is 'fail better', as Beckett recommends."
