Earlier this week, my sister, my mom and I were out for lunch, and we began discussing the importance of speaking multiple languages. I was telling my mom how I plan to learn Portuguese as a third language so that, along with my English and Spanish, I will be able to speak to just about anyone in the Americas. We went on to talk about the polyglots we know who are raised speaking only one language, and how impressive and inspiring they are to have the discipline and desire it takes to learn another language. In a world where the majority of people who go through high school or the equivalent speak at least two or three languages, it's sad that so many people born in the United States have this idea that, because they already speak English, there is no need for them to learn another language. While English can get a person pretty far, why would anyone want to stop there?

Knowing multiple languages is shown to enhance a person's cognitive and analytical abilities, as learning a language is challenging and involves a lot of mental exercise. Some studies even say that learning a second language can significantly delay the onset of many brain-related diseases such as Alzheimer and dementia, compared to speaking only your native language. The process of learning a new language also gives you a better understanding of your primary language. By focusing your attention on the grammatical rules and construction of the language, you get a new insight into your own language.

Aside from better mental health and better understanding, being multilingual gives a person an advantage in employment. In today's business-dominated society, companies that are expanding internationally prefer their staff to multiple languages. By learning a second or third language, you are only making yourself more valuable to companies.

Learning a new language will also make traveling that much easier, as you won't need a translator. Imagine being able to freely find places, ask for directions and order food. Being able to speak with locals will give you a more personal perspective of the country's culture and and how the people live. That beats walking around clueless or being stuck in a resort any day. There is no reason why anyone should be limited to accessing only one culture when there is so much diversity to enjoy. Every culture has so much to offer -- music, literature, film and history. Learning a new language will get rid of so many boundaries preventing you from experiencing all the world has to offer. And with the internet, learning a language can be free and is easier than ever. So what are you waiting for?
