Foreign Language is part of what the US is missing in our education system. Every 1st & 2nd level country except for the US makes learning a foreign language mandatory.
Foreign language is a very important part of:
Understanding your own language
Understanding world history
Understanding of another culture which makes the person more accepting of other people
Expands the ability to reason - comparing the uses of language
And many more.
So try learning a foreign language but only by the natural method like TPRS - Teaching Proficiency thru Reading & Storytelling.
