I majored in Broadcast Journalism and International Relations (a concentration in Sino-Russo relations) with a minor in advertising.
I do not work in any of those fields but I use skills I learned in those courses of study everyday -- listening, thinking quickly, negotiating, team work, concise and clear methods of communication.
However, I honestly think the thing that prepared me most for every single job I've ever had was waitressing. I learned more doing that than I ever did during formal schooling.
