12. Fill your mind with useful skills, not useless crap.
Oh the richness of the irony..
Gotta love it when someone doles out advice, all the while making it obvious that they have no idea what the hell they're talking about.
First of all, there's no such language as "Chinese". And while we're at it, there's also no such language as "Brazilian". There's Mandarin and Cantonese (the two dominant dialects in China), and Portuguese (the official language of Brazil).
Second, you'd have to be a total idiot to fill your brain with all that unnecessary gibberish. Unless you have some kind of sales position which requires you to not only travel but also SPEAK in foreign languages, your time would be far better spent learning skills that will actually have real-world benefits.
You're right -- to some extent -- that there's a global economy, but that's just one of those nonsensical buzz phrases which mean absolutely nothing. Since the inception of currency and trading, there has always been a "global economy". It's not new and certainly not worth getting excited about. Sure as hell isn't worth filling your head with languages that you'll never use except maybe to say "hello" or "thank you" to somebody.
Third, if you want to focus on language, spend your time perfecting your English speaking and writing skills. It's the universal language spoken in nearly every part of the world. That's why children all across China, Europe, India, and even Africa are taught it from a young age, because everyone knows that without a solid English foundation, you have zero chance to compete globally.
