Books

I'm not the original commenter, but I am from Germany and was not raised other than learning English from fifth grade onwards. This was just the basics though, the bulk of my English proficiency comes from playing games, watching shows and movies and reading in English. In the beginning I did it to improve my English, but the German synchronization in videogames was especially bad, so I only ever play games in English, and adopted this practice for other types of media as well. On the rare occasion I find German books I like, I read it in German though, for example the fantasy books "Die Zwerge" by Bernhard Hennen.
