How to learn a language?

The fastest way to learn a new language is to live in a country where it is spoken. I am learning Spanish so ideally I would move to somewhere in Latin America. It would probably be Antigua in Guatemala. I think if you have to stay in your home country it would be good to go to a language class. You could try the book and disk method if you couldn't do this. I learned French at school and day trips France and listenign to French radio helped.

I think one of the best ways to learn a new language is to be totally immersed in it. When you go to a country and you don't speak any of the language, after you've been there for a bit you start to pick things up pretty quickly. It's easy to learn fluidly when you are constantly being exposed to the language and in a position to be using it.

For me, the best way to learn a new language is to find some good text books, get a good compiler, and then start coding. Make a program that you find to be useful and/or fun.
