text:  pay attention to each object, which will exhaust you. You should just walk through it and notice everything that you see and take it all in. That is great advice because I have done that accidentally with the Grand Gallery. That's a quarter mile long, I believe, the longest gallery of art anywhere. And I don't know the names of these painters. I don't care about any particular one. But I just walk through there and now I know what I'm doing. Filter feeding.
