I have always been a great believer in today. Most people live either in the past or in the future, so that they really never live at all. So many people are busy worrying about the future of art or society, they have no time to preserve what is. Utopia is in the moment. Not in some future time, some other place, but in the here and now, or else it is nowhere.
