Unless you've a lot of passion about this, you're not gonna survive. You're gonna give it up. So you've got to have an idea or a wrong that you want to right that you're passionate about, otherwise you're not gonna have the perseverance to stick it through. I think it's half the battle right there.
Steve JobsPeople 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.
