I start work at 5 in the morning and I have a wicked insomnia problem.

Shane Salerno and I adapted my book Savages together, and I learned a lot about adaptation. I think it's an extremely difficult thing to do; adaptation might even be more difficult than writing an original screenplay. It's so much a matter of choices, making choices of what to leave in. It was an education.

We need to do something about gun violence in America. But every time one of these things happen, we say the same thing, and then we don't seem to be able to do anything. And that needs to change.

With a 660-page book, you don't read every sentence aloud. I am terrified for the poor guy doing the audio book. But I do because I think we hear them aloud even if it's not an audio book. The other goofy thing I do is I examine the shape of the words but not the words themselves. Then I ask myself, "Does it look like what it is?" If it's a sequence where I want to grab the reader and not let the reader go then it needs to look dense. But at times I want the reader to focus on a certain word or a certain image and pause there.

The Americans take a product that literally grows on trees and turn it into a valuable commodity. Without them, cocaine and marijuana would be like oranges, and instead of making billions smuggling it, I’d be making pennies doing stoop labor in some California field, picking it.

That sounds like Anthony Soprano. He has a point. I've said it before: if you're black and you sell dope, you end up in the big house; if you're white and you sell a large amount of dope, you end up visiting the White House. So it's a matter of race and it's a matter of scale, frankly.

I have sat with the mothers who have lost addicted sons. I have sat with families of kids who have been killed in drug-related gang violence. I have been to the prisons. I have seen the effects. At some point in time, I felt I had to do something other than write a novel about it, that I needed to try to make some sort of contribution, at least try to make some sort of difference in the real world.
