What is an unusual habit or small pleasure you are oddly fond of?

I, at first, thought I didn’t have a ritual, but then I remembered that I always get up and make a cup of coffee while it is still dark—it must be dark—and then I drink the coffee and watch the light come. And she said, “Well, that’s a ritual.” And I realized that for me this ritual comprises my preparation to enter a space that I can only call nonsecular … For me, light is the signal in the transition. It’s not being in the light, it’s being there before it arrives. It enables me, in some sense.

I then converted a bathroom, seldom used by the family, into a laboratory and spent hours playing with chemistry sets. With the help of an aunt, Esther Molina, who was a chemist, I continued with more challenging experiments along the lines of those carried out by freshman chemistry students in college.

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!”

Long years ago, sometimes it seems many lives ago, I was at Oxford listening to the radio programme Desert Island Discs with my young son Alexander. It was a well-known programme (for all I know it still continues) on which famous people from all walks of life were invited to talk about the eight discs, the one book beside the bible and the complete works of Shakespeare, and the one luxury item they would wish to have with them were they to be marooned on a desert island.

Listening to the sound of rain. Almost every time it rains, I start recording it. Almost each day. What else? Sensing the movements of the wind. Those very subtle things give me so much pleasure.
