Art was, seriously, the only thing I’d ever wanted to own. It has always been for me a stable nourishment. I use it. It can change the way that I feel in the mornings. The same work can change me in different ways, depending on what I’m going through. For instance, somebody I like very much indeed is Frank Auerbach. I think there are some mornings that if we hit each other a certain way — myself and a portrait by Auerbach — the work can magnify the kind of depression I’m going through.
