"Desire is everything - whether it's to get something, get somewhere, do something, achieve something, eat something, have sex with something. It's a motivational force. The progression to fulfilment is extraordinary: that between-world feeling, sort of like crossing over, not just in regard to sexual sorts of things, but in regard to anything - art or politics, science sometimes. It's just that once it's achieved, there's nothing. That moment of desire between the thought and achieving the thought - that's a good moment. That's a beautiful moment."
