Today the English language has a status of a lingua franca. Whenever you meet someone from another country, in case you don't know their native language, you try to communicate in English. And learning it at school is very beneficial for several reasons.
Firstly, you are young enough to quickly absorb everything that was said. It's easier to pick up a language while you're still a kid, rather than in adulthood. Secondly, you have a lot of time - whole 11 years! - to learn the language, so when you grow up you will already speak fluently. You won't look for cheap courses, because you had the chance to do that earlier and (probably) for free!
Though, I don't want to stop. Next language I want to learn is French. It's very beautiful and also widespread in various countries. To achieve that, I need to work hard and even make it a habit, so I would start doing it on a daily basis.
