It seems to me that learning English is very essential. In fact, English is becoming the most popular language in the world. In my opinion, there're a lot of benefits. The main are that you can get a well paid job abroad, travel around the world and socialize with people of different nationalities and make friends. It's a great chance to develop yourself as a person, to be open-minded. Also the most important is that you'll have the opportunity to listen to music, read the books, watch movies in English, I believe it's the best way to know a new words and expressions. Without any doubt, it can give you a chance to live abroad, if you'll really want it.
