That's been one of my mantras - focus and simplicity. Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple. But it's worth it in the end because once you get there, you can move mountains.

Our DNA is as a consumer company - for that individual customer who's voting thumbs up or thumbs down. That's who we think about. And we think that our job is to take responsibility for the complete user experience. And if it's not up to par, it's our fault, plain and simply.

That's always been in my mind my metaphor for a team working really hard on something they're passionate about. It's that through the team, through that group of incredibly talented people bumping up against each other, having arguments, having fights sometimes, making some noise, and working together they polish each other and they polish the ideas, and what comes out are these really beautiful stones.

I met Woz when I was 13, at a friend's garage. He was about 18. He was, like, the first person I met who knew more electronics than I did at that point. We became good friends, because we shared an interest in computer and we had a sense of humor. We pulled all kinds of pranks together.

Our approach is to think of companies not as businesses but as collections of people. We [Apple]want to qualitatively change the way people work. We don't just want to help them do word processing faster or add numbers faster. We want to change the way they can communicate with one another. We're seeing less paper flying around and more quality of communication.
