It's not a quantifiable discipline in any way, it's not a precise discipline, and your response to some painters will be much stronger than to others. Some painters who have great reputations like Watteau, for example, for me, I... I don't know where the magic lies; I've never seen it. I still can't see it. Other painters whom I puzzled over when I was younger I can now look at with much greater perception. And that's just a matter of never closing your mind to anything.

I do close my mind to music. I listen to the music... I get the most enjoyment out of the music that I've always listened to. I don't want to listen to anything new. I don't want to dig up the obscurites of Donizetti... I've never heard that, I knew it existed but: must go and see it? No, no, no. It'll be bad tum-ti-tum-ti-tum stuff and you're just ticking it off on the list. No - I want to go and see Rosenkavalier for the 55th time.

But pictures are a different matter. Pictures - I'm always prepared to look again. That's where my life is.
