A writer is, after all, only half his book. The other half is the reader and from the reader the writer learns.
Books are just dead words on paper and it is the readers who bring the stories alive. Previously, writers wrote a book and sent it out into the world. A couple of months after publication letters from readers might arrive. And, leaving aside the professional reviews, it is really the reader's opinions that the writer needs. They vote for a book - and a writer - with their hard earned cash every time they go into a bookstore (or online - that's my age showing!) and buy a book.
If we as writers could predict what readers grab on to, we would write it.
If the reader doesn't understand what you're saying, you're talking to yourself.
Serial novels have an unexpected effect; they hook the writer as well as the reader.
It's interesting when you're doing signing sessions with other writers and you look at the queues at each table and you can see definite human types gathering there.... My queue is always full of, you know, wild-eyed sleazebags and people who stare at me very intensely, as if I have some particular message for them. As if I must know that they've been reading me, that this dyad or symbiosis of reader and writer has been so intense that I must somehow know about it.
Quite often you want to tell somebody your dream, your nightmare. Well, nobody wants to hear about someone else's dream, good or bad; nobody wants to walk around with it. The writer is always tricking the reader into listening to the dream.
Between Malraux, Balzac, and Montaigne, I choose Montaigne. Montaigne will survive all the others, because the essay, meaning direct communication between the writer and his reader, will outlast the novel, by at least a thousand years.
You're looking for ways always as the writer to bring readers into intimacy, you with them with you. Photos can sometimes do the opposite, create distance and perspective, but these somehow didn't. They somehow bring the reader closer.
