I likely diasgree with this statement. Every language is worth learning because it is how we communicate with each other.
English is third most spoken language in the world, after Chinese and Spanish. I think English is leading language on this planet because Chinese and Spanish are spoken only in few countries. There are approximately 370 million native English speakers all around the world. On top that, there are roughly the same amout who use English as second or third language. And let’s not forget about technologies. Nowadays, it’s hard to find a device without built-in English interface. Is is also considered as the language of international business.
In my honest opinion, I’d recommend to learn as many languages as possible. It doesn’t matter if it’s French, Dutch, Spanish, Mandarin, Korean or any other language. It breaks the language barrier between people. Few years ago, some teacher of mine told me that I have to learn as many languages as possible because it is my treasure. The treasure that cannot be taken away from me. Since then I usually visualize language as a key that unlocks the world to me. Knowing other languages greatly increases the number of people on the globe with whom you can communicate. You can have friends, pen pals and spouses from all over the world.
In addition, people with multilingual skills look more attractive to employers. Chances are that knowing languages will open up employment opportunities that you would not have had otherwise. With greater language skills you can easily raise the amount of your salary. There are other advantages of learning languages. If you know foreign language it gives you the opportunity to step outside your comfort zone and have a deeper understanding of foreign cultures through books, songs and other aspects of culture. Any language is wonderful way to expand your horizon. In conclusion, we are only in the beginning of the journey...
