Learning a language is a real great step that a person takes to improve his status quo. Let me take you through a short and crisp story. Once a sailor landed in a new land, the inhabitants saw him as a threat and they wanted to kill him. When they tried to attack him, he spoke in their native language and all of them very formally greeted and received him thinking he is also one of them. This short story will tell you about the importance of languages. I can help you with any four of these south Indian languages; Hindi (National language of India), Tamil (one of the oldest languages in the world), Telugu and Malayalam. Good luck all!
