…is the name of one of the late, great Terry Pratchett’s books, in which he asks “Why do you go away?” I love his answer: “So that you can come back. So that you can see the place you came from with new eyes and extra colors. And the people there see you differently, too. Coming back to where you started is not the same as never leaving.” 

Marcel Proust said the same thing, I guess: “The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.” 

Food for thought, isn’t it…
