I have never felt the need to trash talk, and I'm not going to start now! I just quietly do my job and then quietly step into the ring to showcase what I can do. And one thing is for sure: I'm going to leave it all in the ring. I've always had such a will to win, and I always give my heart and my soul, so I don't need to change who I am.

I was going to say work on what you love, but that's not really it. It's so easy to convince yourself that you love what you're doing — who wants to admit that they don't? When I think about it, the happiest and most successful people I know don't just love what they do, they're obsessed with solving an important problem, something that matters to them.

The life of a jazz musician is a difficult life, because you want to play, you want to be, you want to get to the inner spirit and sometimes you drink or you use drugs or you smoke a lot. You do all these things to try to get the spirit out. So it’s a difficult existence and a lot of the great people that I have known, and in history, they kind of over-indulge, and they never sort of are able to balance their musical life with their personal life. Maybe it’s not necessary to do that. That is another question, I don’t know, but I’d like to see young musicians coming up that don’t smoke and that don’t drink to excess and don’t use drugs, and don’t sort of debilitate themselves. I think that’s where we should go. I think that is what guys should be doing. I don’t think you have to drink and use drugs to play good jazz, but that’s been the model for so long that a lot of guys get caught up in that, you know.

Don’t romanticise your “vocation”. You can either write good sentences or you can’t. There is no “writer’s lifestyle”. All that matters is what you leave on the page.

I didn't see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.

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.

Technology is nothing. What’s important is that you have a faith in people, that they’re basically good and smart, and if you give them tools, they’ll do wonderful things with them.

We spent some time in our family talking about what's the trade-off we want to make. We ended up talking a lot about design, but also about the values of our family. Did we care most about getting our wash done in an hour versus an hour and a half? Or did we care most about our clothes feeling really soft and lasting longer? Did we care about using a quarter of the water? We spent about two weeks talking about this every night at the dinner table.

Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

One of the saints in my life is this woman named Imogene Hill, who was a fourth-grade teacher who taught this advanced class. She got hip to my whole situation in about a month and kindled a passion in me for learning things. I learned more that year than I think I learned in any year in school.
