I speak Hebrew (native) and English (...good enough).
Learned few words in French before I gone to Hellfest (a metal festival in Clisson), where I had a great time. I expanded my french a bit before going for the second time.
I found myself enjoying learning a new language, so why stop? Arab and Russian might be more useful where I live, but for now I focus on French because I have a headstart in that department, and my main motive is the FUN in learning rather than practicality.
