Great engineers are a huge multiplier.

Sometimes life's going to hit you in the head with a brick. Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did.

At Apple, people are putting in 18-hour days. We attract a different type of person—a person who doesn’t want to wait five or ten years to have someone take a giant risk on him or her. Someone who really wants to get in a little over his head and make a little dent in the universe. We are aware that we are doing something significant. We’re here at the beginning of it and we’re able to shape how it goes. Everyone here has the sense that right now is one of those moments when we are influencing the future.

My philosophy is that everything starts with a great product.

So let's not use a stylus. We're going to use the best pointing device in the world. We're going to use a pointing device that we're all born with - born with ten of them. We're going to use our fingers. We're going to touch this with our fingers. And we have invented a new technology called multi-touch, which is phenomenal. It works like magic.

When you grow up, you tend to get told that the world is the way it is, and your life is just to live your life inside the world. Try not to bash into the walls too much. Try to have a nice family life. Have fun, save a little money. That's a very limited life. Life can be much broader, once you discover one simple fact, and that is everything around that you call life was made up by people who were no smarter than you. And you can change it. You can influence it. You can build your own things that other people can use. Once you learn that, you'll never be the same again.
