“ I missed the future. Obviously I knew even before his recurrence that I'd never grow old with Augustus Waters. But thinking about Lidewij and her boyfriend, I felt robbed. I would probably never again see the ocean from thirty thousand feet above, so far up that you can't make out the waves or any boats, so that the ocean is a great and endless monolith. I could imagine it. I could remember it. But I couldn't see it again, and it occurred to me that the voracious ambition of humans is never sated by dreams coming true, because there is always the thought that everything might be done better and again. ”
