When I was in college, I met a starting-out Hollywood director who had just graduated college herself many years before.  She encouraged many who weren't sure of their plans after college to just travel!  And her advice surely has opened-up my mind so vastly and amazingly from the insular comforts of home.  Yes, home is always great to bask in, but seeing the globe takes you on an adventure and truly makes you feel alive!  So yes, everyone: Travel!
