Learning a language?

OK, what is the best method for learning a language? The precise language is French, but a more general method would be great as I will be living in Belgium and need Dutch and German in the next few years.

I have the basics down, am enrolled in a local language course (quite basic, but hey), and have a grammar book. Any more tips?

What's an Icelandic language? Dutch is a Germanic language (as is English), and whilst they deny it, it is like an anglicised German. I found it really easy to learn, far more so than German. It is rater by most rankings as the easiest to learn for English speakers, but of course it depends what languages you currently speak, and your exposure as well (French resources are a lot more common than Dutch!)
