It may be, in fact, that in describing the torturous process she goes through (and, by implication, gone through by other authors, albeit in different ways), she is in fact warning aspiring writers away from pursuing the craft as a way of life. On the other hand, in terms of the second alternative audience, there is the sense that she may in fact be writing for other writers already established in their practice with the idea of encouraging them, of saying they're not alone in their idiosyncratic ways of approaching and/or avoiding the work. The point is not made to suggest that these contrasting target audiences are mutually exclusive. It is, in fact, a manifestation of the author's skill and experience that she is evidently able to speak to such diverse audiences in such a way that both can potentially understand.
