learnig foreign languages I agree that learning languages can be addictive and you are happy. However, the problem is that if you are addicted to something, your behavior tends to be reckless. You might lose "sense of balance". Aspiring for too much happiness might end up with desperation. Sometimes it is difficult to decide on how many languages to learn and how to allocate your precious time to each language. I imagine that many polyglots are worrying about this problem all the time.
