Focus is a matter of deciding what things you’re not going to do.

John Carmack

People think focus means saying yes to the thing youve got to focus on. But thats not what it means at all. It means saying no to the hundred other good ideas that there are. You have to pick carefully. Im actually as proud of the things we havent done as the things I have done. Innovation is saying no to 1,000 things.

Steve Jobs
