Effects of studying abroad on my future career!

I am not sure what I want to do after graduation. However, I am interested in either being a teacher or working in a diplomatic/IR position within some kind of company. Any psychology knowledge at all will assist me in better understanding people’s motivations, and I can then perhaps accommodate their needs more, especially in fields that are so human-oriented.  

In general, studying abroad allows me to have a better understanding of different cultures. It is an important reminder that humanity is not a monolith. The way I do things is not universal, or even the most effective method. This is a vital understanding in the International Relations field.
