already I found good quotes by R.I. :
"Basically, I can have a terrific time doing nothing. I am quite at ease, and always on the plus side."
Regarding Guston's "really smart paintings"...
"...that God damn Guston...some people call it ' the inner life of the painting'...all that romantic stuff. A good painting has a gathering , interactive build-up . That's what a good Vermeer has, or a raku cup, or a Stonehenge. And when they've got it, they just jump off the goddamn wall at you. They just, bam!"
