The single most important concept of learning a language is personal motivation. I always thought that without that needing a language (because you live in a country where you need to use it, because your girl/boyfriend speaks it, because you want to read some books/watch movies and are only available on a different language) is extremely difficult to get it.
If you think that learning a language would be cool, or it will make a good job opportunity... that strong need is not that present, and everything is way more difficult..
Learning French in France or Spanish in Spain is easier than learning Dutch in Netherlands because everybody speaks at least OK English, there is just no need to learn Dutch. Getting a little desperate and lonely helps a great deal to picking up a language faster
