Well, i haven't given up entirely, but the only way i learn right now is through song-titles. Every now and then i learn a new word, but i can't make any sentences, which i think is more important.
And if a certain word doesn't cross my path often enough, i forget it again.
If i'd be in Japan i would learn a zillion times faster then i do right now. It seems such a waste of time to learn Japanese at this slow pace and not having any direct practical use for it anyway.
