I wrote a while ago about Steinbeck’s pencil obsession as described in his Journal of a Novel, the novel in question being East of Eden. At the end of it he writes a final letter to his editor Pascal Covici, which is described as the first draft of the dedication of the novel and in it he quotes from the prologue of Don Quixote, describing Cervantes as the inventor of the modern novel. This is what Cervantes has to say:
“Idling reader, you may believe me when I tell you that I should have liked this book which is the child of my brain, to be the fairest, the sprightliest and the cleverest that could be imagined, but I have not been able to contravene the law of nature which would have it that like begets like …”
Steinbeck goes on to say something similar, that he has never ‘lost the weight of clumsiness, of ignorance, of aching inability…’ in the process of writing the book. And then continues:
“A book is like a man – clever and dull, brave and cowardly, beautiful and ugly. For every flowering thought there will be a page like a wet and mangy mongrel, and for every looping flight a tap on the wing and a reminder that wax cannot hold the feathers firm too near the sun.”

Writers are constantly negotiating this space between what they imagine they can create and what they end up creating and self-loathing and disappointment are a fairly common response to this gulf. It’s worth remembering that assessing one’s own work is a notoriously difficult thing to do. There’s also the irritating fact that finishing one book does not make writing the next one any easier. However accepting the likely presence of the wet and mangy mongrel may help you to keep going.
I have never kept a diary of the writing of a book and I’ve been thinking recently that I might try. Even if it’s just a sentence a day. Even if I’m already 40,000 words in. But at what point of the day to write it? At the beginning? Or at the end? I don’t know. Maybe I’ll call it: Letters to the Wet and Mangy Mongrel. Truth is I’m more of a Heinz 57 type anyway. So maybe I’m half way there. Have you ever kept a diary of a creative project? What was the experience like? Was it helpful afterwards? Did you learn anything from it?
