Being a humanities student, I think one should learn as many languages as possible. Learning multiple languages does not only help you in better communication in different foreign lands, but they also increase your knowledge of the particular cultures associated with languages, thus making you culturally very rich. Being introduced to the literature of multiple languages is another perk that you get when you learn some foreign language.
Hindi is my mother tongue and I learnt English in school. Along with these two languages, I learnt French and Urdu as well. Knowing four languages for me means being able to see a thing from four different cultural angles, which makes me superior whenever I am with a group of people.
Apart from this, learning foreign language also increase your career prospects to a great degree. Keep in mind that if you start learning a foreign language from an early age, you’d become a master of the language by the time you turn into a job-seeking youth. You will develop a good command over the language with great communication skills.
