what should i do for MBA

I don't think the question is about what should I do, but rather what do you want to do.

If an MBA is what your looking for in order to get a decent paid job, and to gain some international experience, I would tell you to go for it! But make sure the MBA programs you apply to are at countries that are well-endowed in terms of education and funding.

I know that Korea is definitely one of the rich countries in search of international recognition, and they have every right to do it. Schools like Yonsei University, Korea University, and Seoul National University are at the top of the line in terms of business and the staff is definitely qualified to give you both the education and the networks you would need.

Don't know if this is a good start for you, but my two cents are in.

What should you do for an MBA?

Probably the question is, what can you be bothered to do. Since you seem to be want to be spoonfed to be told what you should do for an MBA, the best bet would be screw the MBA and go buy lottery tickets. Hopefully you'll strike something and be able to hire an MBA to actually TELL you what to do...

Yeah, or better yet I just got an email from a Nigerian prince who promises to pay me 10 million euros if I just send him a cashier's check for 500. Maybe that would be more useful for the original poster than an MBA.
