One of my favorite pieces of advice about being a writer came from a very formative teacher I had as an undergraduate, named John Hersey. On our last day of class together, which was also John Hersey last day before retirement, he said, "Remember, the world doesn't need any new writers." Which at first didn't seem like great advice, but when you unpacked it, it was really that it's not enough to be confident in what you do; be conscious of bringing something to the world of readers and writers that it hasn't seen before. Something idiosyncratic.

That's really the essence of what any fiction writer does. Some of it is research-based, but most of it is a really long-term, imaginative, empathetic effort to see the world the way someone whose experiences remote from yours might see it. Not every writer works that way; some writers make a wonderful career out of writing books that adhere very closely to how they view the world. The further I go with this, the more interested I get in trying to imagine my way into other perspectives that at first seem foreign to me.

I once saw John Updike get in front of a crowd and read a story that he'd written in 1958, and I just thought, I can't even look at stuff I wrote a year ago, I can't believe he's doing this.

Luckily for you, you can close the book The Postman Always Rings Twice and break out of it, and James M. Cain can't. I can't think of any redeeming feature he has, but he's extremely compelling.

The Postman Always Rings Twice that's a book that I think every writer should read - that has to do with technique. But it's also a novel narrated by a guy who has decided by page 11 that he's fallen in love with a woman, and they're going to murder her husband so they can be together. There's nothing remotely likeable about him, but James M. Cain brings you so far into his head that, at a certain point, you have that uncomfortable but also thrilling sensation of seeing things exactly as he sees it.

I seem to have a talent for writing endings that seem just right to me but that frustrate other people.

I hesitate to say yes - I had writer's block, because I know there are people who've had really serious cases of it, and I've never been paralyzed like that, but I definitely get blocked sometimes. More than periods where I don't write anything, I have periods where I just write junk and I know I'm writing junk but I can't stop.
