Start it at no particular time of your life; wander at your free will all over your life; talk only about the thing which interests you for the moment; drop it the moment its interest threatens to pale.
Mark TwainYou know that kind of quiver that trembles around through you when you are seeing something so strange and enchanting and wonderful that it is just a fearful joy to be alive and look at it; and you know how you gaze, and your lips turn dry and your breath comes short, but you wouldn't be anywhere but there, not for the world.
Mark Twain
