The only way to keep a dream, any dream at all, to keep a dream perfect and rosy and intact and unsullied is never to live it out. The moment you carry out any of your dreams or your fantasies - travel around the world, climbing a high mountain, buying a new house, writing a novel, carrying out a sexual fantasy, traveling to an unknown country - the moment you carry out your dreams, it's always, by definition less perfect and rosy than it had been as a dream. This is the nature of dreams.
