Know what you’re getting into before you go, or if you didn’t before, then do it now. Research the web, buy some books, watch local movies, and learn the language. It will help you have some idea what you’re getting yourself into. Note on learning the language: it will be hard at times and you’ll feel like a two-year-old babbling incoherently, but not only will you gain a lot of insight into the culture by learning the language, you will also be able to function better. So, be prepared to look foolish and give it a try.
