I'm as proud of many of the things we haven't done as the things we have done. Innovation is saying no to a thousand things.

I would trade all of my technology for an afternoon with Socrates.

Pointing is a metaphor we all know. We've done a lot of studies and tests on that, and it's much faster to do all kinds of functions, such as cutting and pasting, with a mouse, so it's not only easier to use but more efficient.

If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, it's likely that no personal computer would have them.

These technologies can make life easier, can let us touch people we might not otherwise. You may have a child with a birth defect and be able to get in touch with other parents and support groups, get medical information, the latest experimental drugs. These things can profoundly influence life. I'm not downplaying that.

Ask for feedback from people with diverse backgrounds. Each one will tell you one useful thing. If you're at the top of the chain, sometimes people won't give you honest feedback because they're afraid. In this case, disguise yourself, or get feedback from other sources.

I've read something that Bill Gates said about six months ago. He said, ‘I worked really, really hard in my 20s.’ And I know what he means, because I worked really, really hard in my 20s too. Literally, you know, 7 days a week, a lot of hours every day. And it actually is a wonderful thing to do, because you can get a lot done. But you can't do it forever, and you don't want to do it forever, and you have to come up with ways of figuring out what the most important things are and working with other people even more.
