In my opinions, learning a second language can help us step out of our comfort zone.
As we learn another language, we start to mingle with people from other countries and cultures.
Because of that, we learn to understand each other and learn to embrace the differences.
It is certainly not easy to learn a new language.
But if you put effort into it..
day by day, you will be amazed by yourself how far you have come.
This will always be my favourite quote:
"If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart." Nelson Mandela
