Need a little motivation to study? Here are some reasons why learning a language is beneficial.
Brains of bilingual have better executive function
What does this mean? The brain of bilinguals performs better on certain tasks that require planning and problem solving. This happens because the bilingual is forced to change languages constantly; this constant change requires the brain to pay greater attention to its surroundings, making it more efficient over time.

Improves job prospects
Research has shown that bilinguals in the same function as monolingual earn more. And the international expansion of companies makes people who speak more than one language more attractive to the job market.
Tourism and open-mindedness
In addition to facilitating communication in travel, speaking another language opens your mind to new things. Humans of course get uncomfortable when they are in a different environment and experience new things. However, people who speak more than one language are naturally more receptive to what is different.
In short: speaking more than one language improves your mental health, making your mind sharper. It improves the prospects for a good job and salary, and open your mind to the world! Do you need more reasons to learn a new language?
