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.

Everyone here has the sense that right now is one of those moments when we are influencing the future.

I'm an optimist in the sense that I believe humans are noble and honorable, and some of them are really smart. I have a very optimistic view of individuals.

Bottom line is, I didn't return to Apple to make a fortune. I've been very lucky in my life and already have one. When I was 25, my net worth was $100 million or so. I decided then that I wasn't going to let it ruin my life. There's no way you could ever spend it all, and I don't view wealth as something that validates my intelligence.

Be a yardstick of quality. Some people aren't used to an environment where excellence is expected.
