If you could sustain your interest in what you are doing, you are an extremely fortunate person. What you see very frequently in people’s professional life, perhaps in their emotional life as well, is that they lose interest in their Third Act—you sort of get tired, and indifferent and sometimes defensive. And you kind of lose you capacity for astonishment. And it’s a great lost because the world is a very astonishing place. I think what I feel fortunate about is that I am still astonished. That things still amazed me. I think that’s the great benefit in the arts that the possibility for learning never disappear—where you basically have to admit you’ll never learn it.
