When I say "do it," I don't just mean go study abroad in Barcelona, that should be a given. When I say "do it," I mean fully immerse yourself and make sure you are uncomfortable as often as possible. It sucks that the majority of kids travel for the sake of Instagram, or are simply doing the things that they are already comfortable with... those are not the things that make you grow as an individual. I went as a sophomore, and as most kids go as juniors, I went not knowing anybody on my program. This was definitely the right decision as I was forced to step outside of my comfort zone to create relationships that may end up lasting a life time. I highly suggest you study abroad somewhere, I just hope you do it the way that it should be done, not the way that everyone else does it.
