To want is to have a weakness.

The film [Payback: Debt and the Shadow Side of Wealth] opens with an Albanian blood feud and goes on to delve into, for instance, prison systems, underpaid tomato pickers, the gulf oil spill. It's all woven together in a sensuous, oblique way that's not the same as the single-message kind of documentary we're used to, with an "answer" at the end. It's more like an exploration. Sort of like what you do with Birth of a Nation.

I never have [suffered writer’s block], although I’ve had books that didn’t work out. I had to stop writing them. I just abandoned them. It was depressing, but it wasn’t the end of the world. When it really isn’t working, and you’ve been bashing yourself against the wall, it’s kind of a relief. I mean, sometimes you bash yourself against the wall and you get through it. But sometimes the wall is just a wall. There’s nothing to be done but go somewhere else.

I began writing at the age of 5, but there was a dark period between the ages of 8 and 16 when I didn't write. I started again at 16. And have no idea why, but it was suddenly the only thing I wanted to do.

Publishing a book is like stuffing a note into a bottle and hurling it into the sea. Some bottles drown, some come safe to land, where the notes are read and then possibly cherished, or else misinterpreted, or else understood all too well by those who hate the message. You never know who your readers might be.

Some days I do appreciate things more, eggs, flowers, but then I decide I'm only having an attack of sentimentality, my brain going pastel Technicolor, like a beautiful-sunset greeting cards they used to make so many of in California. High-gloss hearts. The danger is grayout.
