Thinking of learning a second language in order to advance your career or expand your business? Well,  you have an important decision ahead of you right now, namely, which of the many global languages will be the most useful.

When thinking about learning a second language, be it for business or pleasure, one of the most important questions is to ask is which one will be most useful to you. The answer to that usually comes down to one of two things: where in the world are you aiming to go and what is the common language used there.

With the rise of globalization, however, sometimes the “importance” of a language isn’t necessarily confined to where it is spoken. Rather, what makes a language important to learn is how fast it is growing.
