It's ok if you don't know more than one language, or if you don't want to learn another. I'm here to let you know what you're missing, and hey! Maybe this'll motivate you to try learning another one.
1.Going to countries where they don't understand your language.
Let's say your going to... France! They don't really speak a lot of English, so it would be awkward to be lost there and get no help.
2. Opportunities!
The more languages you know the better! There are a lot of national programs and knowing more than 1 language could grant you a place there or win you a place in a "4 month transfer" program to another country!
These are onlly some of the advantages,and if this doesn't motivate you, then you can stay in your monotone life! Have a great day :)
