Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking, and don't settle. As with all matters of the heart, you'll know when you find it.
For the past 33 years, I have looked in the mirror every morning and asked myself: "If today were the last day of my life, would I want to do what I am about to do today?" And whenever the answer has been "No" for too many days in a row, I know I need to change something . . . almost everything— all external expectations, all pride, all fear of embarrassment or failure—these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose.
One of the things that really hurt Apple was after I left, John Sculley got a very serious disease. And that disease—I've seen other people get it, too—it's the disease of thinking that a having a great idea is really 90 percent of the work. And if you just tell people, 'here's this great idea,' then of course they can go off and make it happen. The problem with that is that there's a tremendous amount of craftsmanship between a having a great idea and having a great product.
People think focus means saying yes to the thing you've got to focus on. But that's not what it means at all. It means saying no to the hundred other good ideas that there are. You have to pick carefully. I'm actually as proud of the things we haven't done as the things I have done. Innovation is saying no to 1,000 things.
