Great interview in The Sycamore Review with Andre Dubus III, who said in the response to what was he working on at the time of the interview:
I could tell you, but I’d have to kill you. I can never talk about a work in progress. It’s like masturbating before you make love. When you are writing a story you are pregnant with the story and you have to protect it until it’s ready to come out. I can tell you this: I’m working on a novel.
And for advice to struggling writers, this:
Honestly, if I had a divine premonition that I would never be published again I would still write. It’s a better day to have written badly than to not have written at all. If you’re writing four, five or six days a week because you can’t help yourself, the world is eventually going to take notice.
