Learning another language is very fun! It's a brain challenge that not always is easy to keep it in mind. Sometimes at the time I need it or when I'm in front of a native person I just forget it.... A language is a sea of words, phrases, and expressions to handle. However, it's really nice to learn a new language, because open a door to know more about other culture, meet people and see the world with a different point of view. The most you practice, the most you'll get.
