Of the gladdest moments in human life, methinks, is the departure upon a distant journey into unknown lands. . . . afresh dawn's the morn of life. Again the bright world is beautiful to the eye, and the glorious face of nature gladdens the soul. A journey, in fact, appeals to Imagination, to Memory, to Hope — the sister graces of our mortal being.

Sir Richard Burton, Exuberance by Kay Redfield Jamison
