For every painting, I first use the one-quarter inch masking tape to create the grid, dividing the surface across equally. There are four stages of taping. It begins with taping one layer on the whole canvas vertically, then proceeds the same horizontally. The next thing is to apply the selected color with a small brush, then remove the tape. Repeat this same process on the unpainted squares one more time vertically, then horizontally, then apply the last layer of colors. What I love is the degrees of surprise every time; to take each layer of tape off the canvas is to reveal new worlds of optical symphony.

I don’t know. How do you start a project?

It can be combining something disparate. With Greenberg , for example, I had the idea with the character and I wanted to make a movie in L.A. and about L.A. Then I put the two things together and that was the movie. With Francis Ha I wanted to do things in black and white, in New York, and with Greta Gerwig. These are the more conscious things.

I was about to answer cheesily, “It starts me,” but it actually does. I search. I put in a lot of time reading, taking notes, writing in that grasping way that feels mostly wrong. Usually it begins with an image and then the voice comes. Once I have the voice, the book presents. Annie Ernaux talked about it as channeling, and I don’t want to over romanticize it, because there’s a lot of bodily discipline that goes into the making. But I do think that, for me, that’s how a first draft feels. It’s like just keeping up with the voice in my head, being true to it, clinically so—like a pact. I love that first draft, because it’s pre-scrutiny, pre-analysis.

In my own life I think there are times when I’m not in the mood to write, but I don’t consider that to be writer’s block. If I really don’t want to enter my own book in progress, I’ll try to think about why and find a way around that. So I start from the beginning cleaning it up. Almost treat it like it’s a messy room and clean it up. Or if there’s a scene that I don’t want to write because it bums me out, maybe I’ll just work on a different scene and come back to it. Or I’m having trouble writing because I haven’t done enough research. So I go do the research. I try to troubleshoot, or figure out what the underlying reason is.

I think that’s an instinct.
