A Good idea to learn English in a funny and effective way.

First of all this is not my idea!
Yesterday I was reading an eBook on the beach.
The title was something similar the object of this note; I don't remember well.
Among all the advices suggested in the book that one for me I think the best one is this:
If you can go in England to improve your English don't take an frequent there a course of english course, instead, choose an activity that you like and do it there. For e.g. do a martial arts course or a cooking course or whatever you prefer. In this way you are doing something that isn't boring as like an English course sometimes can be and at the same time you are interacting with native English speakers in a real life situation. Bye.

Great job, this is totally clear.  Will you be able to travel to an English speaking country to help you learn?  I wish I could live in a Spanish speaking country for a while to improve my Spanish, but I have to make a living.
