I came across this quote from Michael Becker, and felt compelled to share because I feel the same way despite having not done any major travel myself:
"I’ve never understood those who don’t feel that twinge of excitement when they look at a world map — those who don’t feel compelled to walk out their front door and see something new; or to hike to their destination rather than drive; or to see something just because it’s there; or to experience even the small adventures this world has to offer."
He has been writing a series of posts in the New York Times Scientist at Work column detailing his research in Antarctica. I have followed his personal blog, The Dry Valleys for a few years now as I find it interesting. It is a fun read if you have the time.
