That is absolutely the very best way- to go to that country for an extended time and fully immerse yourself in to the language, Culture- everything. You are right. Then, you're forced to learn because that is all there is.

Unfortunately, many people are unable to do so- much like my grandpa. He had to learn via the record album as he worked and saved year after year to be able to go to America.

But if you cannot travel yet, you can do something like that at your home with a little planning- get your friends together who wish to learn and have entire days and weekends where it's nothing but English! You might even be able to find someone in your community who speaks English well who will love to join!

I really love what your nation does. I believe everyone should travel and experience other people's and cultures. I believe travel is the absolute best education.
