For several months now I've been teaching myself Hungarian from a novel I bought in Paris a year ago. It's not set in Hungary, but rather in Italy and the US, so there's no Hungarian cultural information in it, but it cost only 0.20 euros.
I've been wanting to learn Hungarian for a long time, but had so much distraction around me that it was hard to focus on just one language. Now my distractions are fewer, albeit stronger.
