While previously working at Apple, I contemplated transferring to other countries and trying to work there for a little while. When reviewing countries I may be possibly interested in, I limited myself to countries which spoke English commonly. This was a massive mistake because it transferred into my other thoughts of considering pleasure travel.
Nothing could be further from the truth. You do not need to know the language to move to a country! Don't let such a trivial chasm deter you for several reasons:
1. You will learn it as you go along. Living in a country forces you to assimilate and learn the language, customs and how locals approach situations. This builds character, shifts paradigms and develops an appreciation for culture.
2. Technology does most of the heaving lifting. I've been here for three months, hardly speak any Chinese aside from 'thank you', how to say the mall beside my building complex to taxi drivers, and 'take out' when I order food by pointing at a picture! Translation apps, gestures, facial expressions and locals are more than willing to help you out. Most understand you don't speak the language and want to help you!
3. Chances are likely someone around you will speak English, many people in Tianjin do not speak English, but there are certain demographics of people who do. Luckily for me, these also happen to be people my age. When I need help to get a word across, understand something the translate app isn't appropriately converting or otherwise, I specifically look for females my age -- the age group most likely to speak at least some English, and the gender most likely willing to help me :D If they do speak any English, this leads as a great segway into getting their WeChat info: "So, obviously I'm knew around here, and I really appreciate you helping me out. Let me get your WeChat, we can practice language with each other over [insert meal/beverage of preference]." Works every time!
4. You operate in a different mode when there is no escaping your environment. Trying to learn a language while in your home country is difficult because there is no external pressure forcing you to use it. Move to a country which only speaks your target language and suddenly you realize, damn, I feel like eating lunch, maybe I should learn a few things.
Life is an adventure, unfortunately, too many people get stuck in dead end jobs working for people they hate to buy stuff they don't actually want/need. Travel the world, explore yourself, and build the life that you want! Learning a language is great for your brain and a soft step of such an adventure. It'll unleash your communication skills (as you learn the structure and grammar of another language), especially if you are a creative writer because understanding the dynamic of multiple languages will have both subtle and obvious implications in your style.
I've started my Chinese lessons and practice can be in the most subtle places. For example, my TA at work now requires me to count the number of chairs in the classroom before leaving. Even better, today, during the colouring session with my students, I was practicing my counting and a few of them supported me! They were excited to hear me speak their native tongue while learning mine. Or when I go to get my favourite fried rice (which happens way more often than I'll currently admit here), I can practice expressing the food I want, using my manners, greeting them, and practicing the counting again! Learning a language is a lot like maintaining a healthy relationship -- it's the small things which matter. Put a little emphasis on them by paying attention and observing the details and the big picture will work out smoothly on its own.
Basically, save yourself enough money for the flight and cheap accommodations upon arrival, figure the rest out once you land, otherwise you'll be stuck sitting in your room with numerous justifications for delaying and cancelling weighing down. Nah, not our generation. Our parents have shown us a "good job" is nothing but lies, our governments screw us over and the only people we can count on are those who are like us, those adventure seeking, globe trotting, internet connected spirits we meet along our life path! Don't let a self-imposed barrier stop you, build the life you want and benefiting from all this world, and life, have to offer. Only those who take the leap can reap the rewards!
