Hi everyone, thank you very much for all the replies! I think it might be helpful to elaborate a little more about me and what exactly I'm hopefully looking to accomplish.
I've actually lived in China for 15 months during my University thanks to an extended exchange program.
One of the most important factors in finding some sort of new major /or/ a career with my existing one is working abroad. I'm not partial to any particular country (except China, perhaps), but I know I don't want to stay in the US. However, teaching isn't my calling, so I'd like to work abroad in a different sector. I know engineering is huge in China right now, what with it being the next superpower, so I thought that would be the most logical major choice if I wanted to move and work abroad. It's a very solid, solid skill/major that makes me employable in any country that either uses English or Chinese. I should also say, however, that while I enjoy science-y stuff very much and find the idea of being an engineer amazing (especially green tech, I am so into that), I actually really stink at math, and I'm mediocre at science. These are obstacles that can be overcome, however.
Accounting just seems like a solid major for finding employment in a number of Global companies, from which I could hopefully work in one of their abroad offices. I like money, I like budgets and checkbooks, no problems there really. Could get a masters with a few pre-reqs.
Nursing same deal really, though a much more limited choice in working abroad unless at a military base.
Do you see my overarching goal here? It's partly driven by a not-so-unfounded yet slightly paranoid view that I need to somehow escape the USA before it's too late. And I'd like to bring a skill that will allow me to live a moderately comfortable life in any number of countries in an industry that is a little less vulnerable to language/culture mood swings.
That being said, I agree with the poster(s) who said I need to sit down and really hammer out what I want to do and where I want to do it before I worry about how to get there. I'll definitely work on that, but if anyone has any ideas/experience in working abroad in a different industry than ESL, or just more advice after reading, I'd be more than glad to hear it!
