Many years ago, I, myself, was a Model UN delegate. In fact, my high school came to NHSMUN each year. To this day, I give credit to my faculty advisor, who has since become a dear friend, for getting me involved with Model UN, as it directly inspired me to pursue a career in foreign service.

Networking, negotiation, compromise…this is the stuff that makes the world go around. You might not realize it until years from now, but the skills you’re learning here…they might be more important than anything you’ll ever study in a classroom.
