"Passion. As you can see, I've lived quite a long time, which is to say I've been working for quite a long time, which is the same thing. And you know what? In the whole silly business, the only thing that really matters is passion. It comes and goes. At first it comes to you free of charge, and you waste it. And then it becomes a thing to nurture."
