Postgraduate studies

Hello everyone, the topic of this week for this amazing subject is "postgraduate studies"
Really, I haven't thought about study after this five years, but if the teacher gives me this theme, I can make an idea.
After these studies, I think that if I'd must study another thing, I'd like to make a diplomat abroad, in a spanish speaking country in Latin America, just for know other cultures.
The subjects that I'd like to study are something related with open government, namely, the model of governance that emphasizes transparency, innovation, civic participation, among other concepts. I like this theme because it seems very very very interesting, and gives a new comprehension of governance.
Another subject that I'd like to study is financial management because an optimum use of money is crucial for all the organizations; with good use of resources, the institution will be efficient, and it could be implemented all politics and programs.
About the way I'd like to study is part-time, so I could study half-day and travel and know the other half. In the morning, I'd go to the university or institute, to have classes until 1:30 in the afternoon. After, I can go out to eat, go to the beach (if it is the case), meet people, walk in the city, etc.
Anyway, if I don't want to study now, I won't want to study in three years more.
