I am probably the laziest man in town. I never did like studying or practising (ask my teachers). When I hàve to learn something I surround myself with "relating objects" and hope for the best (telepathy...)
When in Siberia do like... or was that Rome? Anyway, at the moment I have a sixty years old grammar, a knyga dlya pyervowo styenya, Zolotaya Ryga (nice! kind of Tilsitter Edam), caviar of course, I love that, and lots of vodka (I don't know whether that really helps but it makes me feel as if I speak fluently Russian...)
And I read a poem of Mayakovsky, proud, clear (and short).
Good man. you should google him.
