I think art is very tricky because it’s what you do for yourself. It’s much harder for me to make those works than, in a way, the monuments or the architecture because those have functions. Architecture, the monuments, it’s a symbolic function, but it’s still you’re solving a problem. The architecture, you’re definitely making art, but it’s surrounded by a problem solving. It’s like math. It’s a puzzle to me. I love figuring out puzzles. The art work, on the other hand, is, “Go into a room and make whatever you want to make.” And it’s very, very hard.
