Architects feel empowered to give opinions about politics and sociology and philosophy without knowing much about it. Kind of in the same way that they think they can design furniture or fashion or utensils for dining.

In the theater, everything is ephemeral. Everything is almost weightless and without a very clear definition of how you made it.

Music, first of all, is completely about abstraction, which is exactly what architecture is not. In a way, it has been incredibly constructive to know what true abstraction is. So you don't fall into the trap of thinking that what you do is abstract.

I play only classical music. My pianos are my only big indulgence, but they're a necessity. When I'm playing the piano is literally the only time I can be completely abstract and disconnected from the regular world and yet be connected - to my music.
