ASounds pretty good. I have a friend who is going to the school of foreign service at Georgetown and she was a great student just like you. What set her apart from others is that she constantly went to El Salvador and did community service over there, and was the representative of a service group in El Salvador here in USA. She was VERY involved and extremely passionate about it. She also knew Spanish very, VERY well (as she is from Central America). Make sure you have that thing that sets you apart from others, especially something that has to do with foreign service.

AI'm thinking an MBA is not what you need for government work - what you're going to want is an MPA or an MA/MS in some high need area. You'll need to narrow down exactly what you want to do in the foreign service arena before you can really make the decision. If you're looking at becoming an area expert then the MBA isn't the toolbox you'll want. If you're wanting to work in economic development then it may well be. If you want to work in international law or humanitarian relief, the MBA may be a hindrance over an MA/JD combination. Redefine your goal into a more specific focus and the degree you need will be easily determined.As for the music dream - that's not exactly a compatible role with your other dream but there's nothing wrong with taking a year or two to follow a dream and see where it leads. An MBA in anything can land you in the music industry business side but they likely won't be paying your 6-figure goal.

AAccountancy and civics aren't so much social studies, if it was philosophy or Psychology thatd be different. But accountancy would come under the Businesses.I suggest you take the engineering route, their much more pracitical and they generally pay more, their generally in demand; also get to build interest stuff.In accountancy and civics you would generally have to use a lot of computing skils, sit behind a computer for a large amount of time; the jobs arent generally in much demand meaning your less likely to find a job in the industries.
