First of all, if you want to be really fluent in a foreign language, you can't leave the books aside. You must find a good book that will help you understand the basic concepts of the grammar, which includes constructions of the sentences, tenses, some basic rules etc. When you get to know it, then you can start to learn by communicating with other people, especially native speakers. It doesn't have to be strictly face to face, you can use lots of internet sites which can help you a lot as well. At least that's what I do when I want to learn a new foreign language.
