LEARNING A FOREIGN LANGUAGE

Which is the easiest way to learn a foreign language? Some people think that the easiest way is to go abroad to learn the native language, another people think that it is possible to learn a language merely by going to lessons or at home by themselves.
To begin with learning by going to lessons, this is a good idea for starting (or to start) to learn a language because it’s a more structured way and also you have the help of the teacher, however this way has some disadvantages, for example if the teacher is not a native one maybe you don’t learn properly the language properly. Whereas on the other hand the alternative / best / other way to learn is go abroad and learn first-hand the language (or learn the language first-hand). This way also has advantages and disadvantages; the first advantage is that it is the fastest way to learn because you don’t have another option to talk and you can learn about how the people live in another countries (or in another country). The worst (better: biggest) disadvantage is that you are far away from home and it can be sad sometimes.
From my own experience I can say that the best and easiest way to learn a language is going abroad. It is true that it has disadvantages but I think the advantages are greater, and you have the possibility to live a new experience and get to know a lovely new people and places.
