Learning foreign languages is especially important nowadays.
The connections between different countries and between inhabitants of different countries increase, so people try to learn languages.
There are also privat origins.
For example one can be interested in foregn culture and have desire to watch favorite tv series or read a favorite book in authentic language, In Russia one learn languages from school and primarily English.
I learnt English in school too, but I think, I had a poor motivation for it, so I speak English hitherto not very good.
At some point I was interested for German und I have been learnt German for three years.
I visited German course and lived four month in Germany, so I speak German now better than English.
At the moment I would like to improve my English.
Though I have difficults with English, I dont lose hope, that I will ever speak and write English fluently.
