I'm as proud of what we don't do as I am of what we do.

And it comes from saying no to 1,000 things to make sure we don't get on the wrong track or try to do too much. We're always thinking about new markets we could enter, but it's only by saying no that you can concentrate on the things that are really important.

Computers themselves, and software yet to be developed, will revolutionize the way we learn.

The seven-inch tablets are tweeners: too big to compete with a smartphone, and too small to compete with an iPad.

I don't think I've ever worked so hard on something, but working on Macintosh was the neatest experience of my life. Almost everyone who worked on it will say that. None of us wanted to release it at the end. It was as though we knew that once it was out of our hands, it wouldn't be ours anymore.

It's hard to tell with these Internet startups if they're really interested in building companies or if they're just interested in the money. I can tell you, though: If they don't really want to build a company, they won't luck into it. That's because it's so hard that if you don't have a passion, you'll give up.

You have to be burning with "an idea, or a problem, or a wrong that you want to right." If you're not passionate enough from the start, you'll never stick it out.
