I have a problem with my ears. I really have a problem. When I was living in the city, I threatened people because of some noise they were making that was bothering me. It sounds psychotic, I know. Once it was a beep from a fax that I heard in the night, very far away. I went to every floor, to every neighbor, putting my ear to the door, until I discovered where the sound was coming from. Then I would tell them, “You have a fax machine that’s making this sound and it’s driving me crazy.” “You’re four floors away from me—how can you hear that?” they said. “You’re crazy, you’re a hysterical woman.” Whatever, call me whatever you want, but I hear it, and I can’t sleep because of it.

Well actually I was at home. I was doing some housework. So I was very surprised.

I call it “stolen time”—there’s nothing more valuable than stolen time. It happens to me sometimes when I’ve set up a meeting at my studio at a certain time and it gets cancelled on short notice. When it happens, I’m like a giddy child. I think, “Wow, I’ve stolen half an hour. It’s so exciting—I can do whatever I want!”

I love going to the tip. A friend reassured me once that if I ever get cancelled, I’ll still have the tip, and she was absolutely right. Even Britney Spears has the tip! It’s never going anywhere, and that’s a nice thought.

The way I work is — I want to not have external stimulation. You can kind of see, on the walls are this light green. I'm told that at mental institutions they use that on the walls. It's like a calming color, it's not something that really stimulates you. What you can't see is the computer here, you only see the screen, but the main thing I worry about in my computer is — it doesn't have to be big and powerful, although I like that — it really has to be completely silent. I know people who work for Google and they have their own small data center at home, and I don't do that. My office is the most boring office you'll ever see. And I sit there alone in the quiet. If the cat comes up, it sits in my lap. And I want to hear the cat purring, not the sound of the fans in the computer.

I've actually felt slightly uncomfortable at TED for the last two days, because there's a lot of vision going on, right? And I am not a visionary. I do not have a five-year plan. I'm an engineer. And I think it's really — I mean — I'm perfectly happy with all the people who are walking around and just staring at the clouds and looking at the stars and saying, “I want to go there.” But I'm looking at the ground, and I want to fix the pothole that's right in front of me before I fall in.
