I’ve been emphasising here the small and the private, because essentially that’s what my work is about. One person writing in a quiet room, trying to connect with another person, reading in another quiet – or maybe not so quiet – room. Stories can entertain, sometimes teach or argue a point. But for me the essential thing is that they communicate feelings. That they appeal to what we share as human beings across our borders and divides. There are large glamorous industries around stories; the book industry, the movie industry, the television industry, the theatre industry. But in the end, stories are about one person saying to another: This is the way it feels to me. Can you understand what I’m saying? Does it also feel this way to you?

I’m a rather slow writer and I have to go to a coffee shop. I turn my back to the crowd in the cafe, so that everyone’s chatting and the noise of the place rises behind me, and then I just keep my head down and churn out my screenplay. I can’t write at home, because I get too lazy. I’ll just want to watch TV or fall asleep. But I’m not allowed to lie down and fall asleep in the cafe, right? So it kind of forces me to work.

It looked like an agricultural frame, something you might grow peas up – a lot of wires and cables strung from posts over a space the size of 57 tennis courts. It was actually built to study radio emission from quasars. I built the prototype and then six of us took two years to build the real thing.

So far they are conforming to pattern, alas! I mean I am suffering from the usual delusion that the play was ready before we went into production. It happens every time. I give my publisher the finished text of the play so that it can be published not too long after the opening in London, but by the time the galleys arrive they’re hopelessly out-of-date because of all the changes I’ve made during rehearsals. This time I gave them Hapgood and told them that it was folly to pretend it would be unaltered, but I added, “I think it won’t be as bad as the others.” It turned out to be worse. Yesterday I realized that a chunk of information in the third scene ought to be in the second scene, and it’s like pulling out entrails: as in any surgery there’s blood. As I was doing it I watched a documentary about Crick and Watson’s discovery of the structure of DNA—the double helix. There was only one way all the information they had could fit but they couldn’t figure out what it was. I felt the same. So the answer to your question is that the rehearsals are going well and enjoyably, but that I’m very busy with my pencil.

Home can never really be a place. It is this thing that you carry inside of you.

The desk helps, now that I have it. I’ve stacked piles of books that I love on it to act as talismans. They help, too. The desk makes me feel like I’m going to work, even though work is located in a cramped but bright corner of my living room. […] I used to think of myself as someone with a great deal of discipline, but I lost it in the air somewhere over the Rocky Mountains. Now, instead of discipline, I have a desk, and every day that I sit at it I dig a little deeper.

Homegoing spans about 250 years of Ghanaian and American history. Some of this history I knew a bit about, but the novel did require an extensive amount of research, which was by far the most difficult part in the process of writing.

Usually, my irrational bargaining goes something like this: I start working at around 10 if I’m feeling motivated, 11 if I’m not. I reread the work from the day before and/or passages that I think I got right in order to try to set the tone. I write a sentence. I read it aloud. I delete the sentence. I look at the clock and wonder if it’s too early to think about lunch. I tell myself that, if I can make it to 300 words, I can break for lunch.

I don't think I really understood that you could choose writing as a profession for many years later. It wasn't really until I was 17, when I read Song of Solomon by Toni Morrison and saw, 'Oh, someone like me, a black woman, can do this ...

I think one of the best things that art can do is to shine a light on dark places, and to hold something up and say: 'This hasn't gone unnoticed. We see this, and we're going to say something about it.'
