There are many ways, depending on where you live, who you are and what part of the language you want to practice. Most people can get their hands on books or newspapers (see below), so this is where to begin. Then you can go to the movies, watch TV or listen to the radio to further practice passive skills. Finally, in many areas you will find people speaking your target language who organize in cultural groups etc... that you can contact to speak a little. Last but not least, you could also travel to the target country once in a while.
