imo-- Seeing the world is vastly underrated, but only for those with the right intellect and sense of adventure. One major litmus test: when you visit a new city, do you (1) try to go to a restaurant or other place that you won't find elsewhere, or (2) do you look for an Applebee's or some other chain that you know?
#1, you'll probably have a great time.
#2, you are a pedestrian rube, so please do the world a favor and stay at home.
