70 vocab words!

So I have now created e-flash cards for 70 vocab words!  I pretty much have the alphabet down and I've memorized probably at least 40 different words.  Unfortunately I haven't made much progress on grammar and I haven't really begun to do much speaking, listening, writing or reading in Russian.  Maybe I need a children's grammar book.  I dunno.  I am making steady progress on the flash cards though.  They are great and convenient!  I like to spend the odd 2-5 minutes here and there but it would be nice to devote a whole day to memorizing vocab.  I mean it would be boring as fuck, but the long term pay off would be huge.
