There is something powerful and magical about learning a language and investing in learning a language which opens doors both in life and business that no other tool can. In a world where technology is bringing cultures closer, language is still the most important tool. Sure, anyone can type a message and have Google Translate it, but have you ever tried translating the translation back into your original language? Tone and emotion are lost and very often the meaning is not what you really wanted to say.
If your only reason for investing in learning a language is just because, then do it and you will see a whole new world open up around you.
