Sort of the problem here, is that it's based on full time (!!) language learning.  Um. ok.  Still some good links for non traditional language study methods.
Since the languages I'm most interested in adding are non-traditional, Catalan and Swiss German, this may be for me.
Tim Ferriss has a list of the most common words and a good strategy for basic language skills. (Too lazy to get link.)
