There are a number of positive reasons for learning a second language. In the past, the only people who bothered to learn a second language were those who desired to travel to other countries, had to relocate to another country, or did extensive business dealings in a particular country. However, more people are beginning to see the benefits of learning another language extend beyond just being able to travel and work.
Children that learn a second language are found to have better cognitive skills and are also better able to acclimate in a foreign culture. Adults who work on learning a foreign language not only learn how to speak and write in a second language, but linguists have found that they actually improve their understanding of their native language. While children are quicker at picking up a second language, with enough practice adults can easily learn how to speak one or two additional languages.
One of the best reasons to learn a second language is to make travel easier. While English is spoken in many countries, there are also many countries that rely on Hispanic or Asian languages. If you know that you will be traveling a lot, whether for business or pleasure, it helps to learn the language you'll hear most frequently when traveling.
Research has shown that learning the language of another country also helps sensitize you to the cultural differences of that country. Many times language shows us exactly how people react in situations or what the people find normal and abnormal within the culture. In some cases, words you may use in your native language would be offensive in another language or disrespectful to the people of that culture.
Learning a second language helps you increase your skills in both the work and academic fields. Some job openings are only for people who can speak certain languages, meaning that the sooner you learn another language the quicker you're eligible for more jobs. Every new job provides you with skills you didn't know before, so a second language only helps you improve and grow as a professional.
Knowing how to speak two languages can also help you academically. Competitive colleges and universities often prefer applicants who are bilingual. If you're competing to get into a top college against people from other countries, you can rest assured that those applicants speak their native language and probably the language of your country. Knowing two languages also helps you appreciate art, music, and film of other cultures and languages. This is beneficial when attending school because it allows you to have more fine arts experiences and gives you an edge over your classmates who only speak their native language.
While knowing two languages for school or work is beneficial, you'll also get a feeling of accomplishment by mastering a second language. Many people impact their own self-esteem by simply tackling the task of learning a language and becoming fluent in that language.
