Reading reading reading reading reading! And translating the stuff you read into your language to make sure that you understand the words. As soon as you have some vocabulary, you start choosing simple texts written in your language and you translate them into the language you want to learn.
Look for documentaries with subtitles on youtube. Or you can use topdocumentaryfilms.com. And of course, look for language partners, so that you can practice your oral skills :)
An other hint: crosswords and hang man!! Effectif and fun :) if you have an iphone or ipad, than you can download crossword-apps.
I which you all the best and fun while learning :)
