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.

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.

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.

Keeping all devices aside 1 hour before sleep, stopping all work chats at Zerodha unless critical after 6pm, and spending time doing what is most relaxing just before sleep (spending time with my son & hobbies) and on weekends has helped me the most with sleep.

It’s often the same with any new, revolutionary thing. People get stuck as they get older. Our minds are sort of electrochemical computers. Your thoughts construct patterns like scaffolding in your mind. You are really etching chemical patterns. In most cases, people get stuck in those patterns, just like grooves in a record, and they never get out of them.

We tried make something much more holistic and simple. When you first start off trying to solve a problem, the first solutions you come up with are very complex, and most people stop there. But if you keep going, and live with the problem and peel more layers of the onion off, you can oftentimes arrive at some very elegant and simple solutions. Most people just don't put in the time or energy to get there.

I think the work speaks for itself. I don't think that people have special responsibilities just because they've done something that other people like or don't like. I think the work speaks for itself. I think people could choose to do things if they want to but we're all going to be dead soon, that's my point of view. Somebody once told me, they said "Live each day as if it would be your last and one day you'll certainly be right." I do that. You never know when you're going to go but you are going to go pretty soon. If you're going to leave anything behind its going to be your kids, a few friends and your work. So that's what I tend to worry about.

The things I'm most proud about at Apple is where the technical and the humanistic came together, as it did in publishing for example. The Macintosh basically revolutionized publishing and printing. The typographic artistry coupled with the technical understanding and excellence to implement that electronically--those two things came together and empowered people to use the computer without having to understand arcane computer commands. It was the combination of those two things that I'm the most proud of.

But the market was changing. The industry was changing. The scale was changing. And in the end we knew we would be either the last company to make it or the first to not make it. We were right on the edge. We thought we would be the last one that made it, but we were wrong. We were the first one that didn't. We put an end to the companies that tried to do that. We certainly made our fair share of mistakes, but in the end I think we should have taken a bit longer to realize the world was changing and just gone on to be a software company right off the bat.

We tend to focus much more. People think focus means saying yes to the thing you've got to focus on. But that's not what it means at all. It means saying no to the hundred other good ideas that there are. You have to pick carefully.
