When I was a kid and started to be obsessed by art in the 1980s, the art world was in this polarity Warhol/Beuys, Beuys/Warhol. Both expended the notion of art extremely, but in very different ways.
I still remember my first Giacometti exhibition, and going back to the museum every day, whenever I could, to look again and again at these long, thin stick figures, so beautiful, so graceful. That, I think, was the moment I became really obsessed by art.
