English is an international language that it is communicated by more than half of the world population.
English language is popular for traveling and communicating with foreigners. If you're going to know the language, then you do not have to ask many questions to foreigners visiting various boring excursions, you'll be able to travel independently.
Thanks to the knowledge of language I think you can make trips to other countries. You'll be able to communicate with people, to learn something new, to improve your knowledge of the language skills.
As fares I know now many films and books are published in English, but until they are translated, it takes a long time. Therefore, with the knowledge of English you can watch movies in origin, it's much more interesting and exciting and also translations are inaccurate. To my mind books are much more interesting to read immediately without translation.
Also, in many professions knowledge of language is required mostly English. Much easier to go to a business meeting without an interpreter to communicate with the colleagues. Do you agree with me?
The most popular songs are in English, and I like them too. They are fast and rhythmic.
When you listen to a song, you begin to think about the translation and to understand its meaning. This inspires you for learning the language and improves their skills.
You can still list the reasons to learn a language, but the most important one for me is my interest! I do my best to speak English well!
