I’m the worst about this. I often don’t know. I’ll have 14 small victories while I’m working on something. I’m like, “It’s done,” and I show it to somebody and they’re like, “Is it?” They ask me a couple questions, or I’ll realize myself like, “I think it’s done,” and then a few days later I’ll realize that, “Oh no, I’m still having ideas about it.”

Something is never done. If time and money and deadlines were no object, people would tweak until the cows came home. Ultimately, I would like to think something is done when I master it and I send it off and I’m so stoked about it. I feel like, “Wow, I really brought this one home.” And then I get the same feedback from the artist, that it is just beyond their imagination. Where it comes back to them, and they get excited about the mixes again. Or if there was something they were worried about, and it gets addressed and sounds better than they would’ve thought.

For me, especially with this last book, I had nothing else to say about these characters from this point in their lives. I felt like I’d reached the end of what they’re telling me—it wasn’t even what they’re telling the story, it’s more what versions of them I needed at that time.

It’s funny you say that because I never have this moment when I feel, “Ah, I’ve finished!” I watch footballers at the end of the match, you know, the whistle goes and they’ve won or lost. Until then they’ve been giving everything and at that moment they know it’s over. It’s funny for an author. There’s never a finishing whistle. It’s not very spectacular.

I was at the Royal College in 1977 and invited to exhibit in the Queen’s Jubilee exhibition. I was over the moon. I’ve had a lucky life. I pinch myself regularly. But every time a work turns out that I feel excited about, that’s the real reward.
