I come from the generation who were taught never to throw things out. I like the idea of hanging on to things and repairing items rather than discarding them. It’s not a question of money, more to do with guarding resources and not being wasteful. My children laugh at me when I sit darning a pair of socks.

The great singer Um Kulthum (actually named Kawkab Elsharq – a superstar of the East) had a major influence on my appreciation of music. On the first Thursday of each month we listened to Um Kulthum's concert – "waslats" (three songs) – for more than three hours. During all of my study years in Egypt, the music of this unique figure gave me a special happiness, and her voice was often in the background while I was studying mathematics, chemistry… etc. After three decades I still have the same feeling and passion for her music.

Until this time I had never been able to drink whisky. I disliked the flavour intensely. I could not understand how so many of my brother officers were so often calling for a whisky and soda. I liked wine, both red and white, and especially champagne; and on very special occasions I could even drink a small glass of brandy. But this smoky-tasting whisky I had never been able to face. ... Once one got the knack of it, the very repulsion from the flavour developed an attraction of its own; and to this day, although I have always practised true temperance, I have never shrunk when occasion warranted it from the main basic standing refreshment of the white officer in the East.

I don’t lead by force, I lead by example. And if I can, set a good example. If I can set an example to my staff and my group, by being punctual, I come to work every morning, walk onto the hospital floor within two or three minutes of the same time every day, and they can depend upon it.

I find that you’re a completely different person as a maker than you are as a listener. That’s one of the reasons I so often leave the studio to listen to things. A lot of people never leave the studio when they’re making something, so they’re always in that maker mode, screwdriving things in - adding, adding, adding. Because it seems like the right thing to be doing in that room. But it’s when you come out that you start to hear what you like.

My favorite method is stopping everything for a moment. It’s amazing how difficult I find it these days to simply sit quietly.

I like to break up days and structure them. You have breakfast, work for two hours on a project, check your emails, work on another project for another two hours and then lunch. Your day has to be a measurable process, in order to minimize aimless drifting. Of course, you can have some days on automatic pilot, and there’s nothing wrong with drifting in and of itself. But you can’t do that every day—you’ll never get anywhere.
