The global language at the moment is English, you'll find this language wherever you go. Hear it on the radio, listen to it in your favourite sons or maybe see it in the movies. It doesn't matter if you are in an Asian country or even an Arab country, you'll still find things translated in English because of how global it is. And so not being able to master such a language is considered a flaw, sometimes people even feel like an outsider when they can't reply the person they're talking to in English. Hence, this is the reason why it's so important to understand this language. In order for you to get to the top, then you should start from the bottom and don't worry, it's not too late to catch up. It will be a rough ride but every step will count.
