Well, I actually asked this question myself a little too late.
It was too late because, by that time I had was already speaking a bunch of languages.
While there are myriad read reasons as to why someone should be learning a language, ranging from Social interaction benefits to adding a skill to your Resume, I have made an attempt to pen down a few of them which are reasonable.
1. Adaptable in Business/work/study
If you are emigrating to a country or a region due to work/studies knowing local language would help you to communicate with the people around and learn there culture, way of thinking and experience there ways.
2. Socializing with Family/Friends/Relatives
Or if your partner comes from another country/language, it helpy you understand your inlaws, relatives and friends and hence helps you socialize better and have a healthy relationship.
If you are one of those who love to travel, and feel the Itch very summer to travel to another country or region, then learning the language of the region you travel makes the difference in your travelling experience. It also helps you greatly in making your holidays more comfortable and enjoying the locality.
Interestingly there is also a spiritual reason to learning languages . Most of the times, the religion we follow are written in a language which we dont speak like Arabic, Hebrew, Sanskrit. What could be more cherishing than understanding your own religion in its own language, rather than reading the translated texts, which are unclear and altered to convey the closest meaning at best.
5. Improve cognitive skills
6. Better/New way of thinking, speaking and writing
“A language that doesn’t affect the way you think about programming, is not worth knowing”.
7. Challenging yourself
For those who love taking a challenge, there couldnt be a better challenge than taking a language to learn.
And the reward stays forever!. Learning a language is a challenge, it takes time, determination, motivation and ability along with lot of mental energy. During the process, you understand yourself better in terms of ability to learn, memorize things, makes you disciplined (if you have structure the learning plan in a certain time) . At the end of it, you come stronger and with a great sense of achievement, which you can boast for rest of your life.
8. To understand Love, Music, History or Art
Every language has its own beauty. While some language are strict with rules (German), others are fun to speak and sing (Spanish).
Language also show how people think and behave. If you love music of a region, or like History of a region, or interested in the Art popular in a region, there can not be greater motivation to learn that language.
9. Better opportunities
Learning a language clearly increase the opportunity to get employed in that geaographical region. Especially if your job has to do something with Public relation, the better you know the language, the greater your opportunities to land up in a lucrative job are.
While majority of people are objective and question the worth of learning a language, there are people out there, who first
plunge into it and have fun with it, without worrying about how they could reap the benefits out of it.
Happy learning !
