The castle and the bricks

“imagine you are building a castle on the hill and you're like, "What would be the most magical, wonderful, mythical experience?" And the other thing you can do is you can look at the bricks around you and you can say, "What can I do with these bricks? How high can I stack them? What can I do?" And I think most planning is often done by looking at the bricks and trying to stack them, and then you can create only so much.”
