If getting what you want, the way you want it, when you want it, is critical to your overall life happiness, then life abroad is probably not for you. Sally, of When Harry Met Sally, would have melted. The key, in my experience, to success in expat life is the suppression of desire. Happiness comes from wanting what you get, rather than getting what you want.
Let's take a simple example: Soup of the day. You ask the waiter what it is and the only word you recognize is "tomato." Great, you think. I love tomato soup. Maybe there are a lot of other vegetables in that soup, too (another key to success in expat life is wishful thinking, but that's for another edition of "Ask Carpetblogger).
The soup comes. It's lentil soup, with tomatoes. You are faced with a choice: disappointment because there are no visible tomatoes in your soup -- only a vague hint of puree -- or complete satisfaction. Yay! Lentil soup! I love lentil soup!
Maybe this isn't the best example because in Turkey, nine times out of 10 soup of the day is going to be lentil and it's totally delusional to think otherwise. But even in Kyiv, when you order steak and get a pork chop, it's best just to accept that pork is probably better for you anyway.
Furthermore, there is a correlation between the intensity of the desire (for a really good bagel, for example) and the barriers that will prevent you from satisfying that desire (no Jews). Do not desire bagels. Be happy with a simit -- there's a simitci on every block. No barriers at all. Don't let the words "pork shashlyk" enter your mind. Ever.
The Buddha said the root of all suffering is desire. It's one of the four noble truths. That dude clearly spent a lot of time abroad.
