There is always a negative side to travel as well. Of course there is the hassle of suitcases, and possibly long tedious hours to be spent aboard aircraft, trains, highways. There is always the threat that once we get to our dream destination, it won't live up to expectations. We might have to give up the comforts of home as we traverse the planet. And maybe, and this is the most scary yet, maybe when we travel we will be forever changed. Maybe once I see the decadence of a wealthy city or the degrading poverty of another, I won't see my corner of the world the same when I get home.
