Travelling dapat memperluas pengetahuan anda. Seperti yang dikatakan oleh penulis asal Inggris, Terry Pratchet, yang menulis “A hat full of sky”, mengatakan
“Why do you go away? So that you can come back. So that you can see the place you come 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.”-Terry Pratchet.
