I speak 4 languages. Russian is my native; I then learned English, Spanish and Portuguese. There's only so much you can learn from books and taking lessons.

I speak 4 languages. Russian is my native; I then learned English, Spanish and Portuguese. There's only so much you can learn from books and taking lessons. My skills really took off to fluency level when I moved to the particular country (US, Mexico, Brazil, respectively) for at least few months (I would say at least 6 months) and practiced with native speakers.
