I think learning new language is very good and have very much benefits,
For example practicing new language for me was like discovery of new ways to express myself,
While one doesn’t have prejudices on how they will express themselves verbally because of new way of speaking this opens up new possibility to explore ourselves in a way we never did before and see how it will go.
This is actually fun, challenging, advancing and realising things about ourselves that we have more capability in communicating, this also extends into languages which we already have learned well, like our native language, and upgrades it into new level,
Where you start to become more multiexpressive and colourful being, this helps in building your character, confidence, social skills, self expression, we start to enjoy ourselves more and trust ourselves.
Definetly do it, it will benefit you spiritually!
