1. Clothes: As soon as you land you need to decide whether you want to fit in or stand out and LOOK like a foreigner. Sometimes the colour of your skin decides that for you. But all is not lost, a few casual adjustments to your wardrobe and you can fade into the crowd. The other option is easy: just keep wearing whatever you bloody like no matter what the temperature is or how many weird stares you get. This is called the permanent tourist method. 2. Food: Either start loving the food in local restaurants or LEARN HOW TO COOK LIKE YOUR MOM. For most of us the latter is impossible, so you're left with the more adventurous option - tolerate the local food and surprise yourself everyday with new discoveries. E.g. "Yum!," or "I'm never going to that place again!" or "Oh God the horror..." Beware: after several months your adventurous nature may disappear.
3. Transport: The most fun part of any new country is the unpredictable and new buses, taxi's, roads, and train services. If you are from a country with a horrible and inefficient system you will appreciate the calm monotony of a dependable service. If you are from a country with awesome transport you will hate it and need to improve your survival skills.
4. Night Life: If you manage to make cool friends in the foreign country you will go to to the best places in town which are awesome no matter where you are (seriously, anywhere). If you don't make cool friends then you can meet other losers like yourself and stumble around the foreign country in an adventurous and potentially dangerous (in some places) manner. This is also okay.
5. Weather: If you are very good at living in a foreign country and manage the first four steps easily, then I can assure you that weather is always a problem. If you are from a very cold country you will love the warm and unbearably hot temperature and bake yourself pink everyday until you fall sick. If you are from a hot country you will hate the frozen foreign land and wonder why God has forsaken these people.
6. Language: This is the deal breaker for most people. The most practical thing to do is to choose a foreign country where you KNOW THE LANGUAGE. If you are stupid you will not do this. Instead you will try to learn an absolutely new language and in some cases, new SCRIPT, and struggle to do simple tasks like buying bread and reading the menu. You are truly an adventurous spirit because after one year of this you will either become an expert or start hating this complex and mystical foreign language. In extreme cases you can just use sign language, with a calculator, and point at things (this is also part of the permanent tourist method and locals will secretly or openly hate you depending on how polite the foreign country is).
Mastering these six steps will make you an expert in living in foreign countries, and don't let the negativity fool you, it's actually awesome fun! (sometimes).
