Improved English
English is based on several different types of Latin-based languages, so learning a new language may lead to increasing your vocabulary or overall speech.
Increased creativity
Learning a language can be like completing a complicated puzzle; there might be a number of words you might struggle putting together, but you learn how to creatively manage the new words in your new language.
Learning a new culture
Every language is attached to a specific set of cultures and you are more likely going to learn about the areas that speak the language you are learning. You can also improve your language abilities by going to meetups and watch videos that focus on those communities.
New career opportunities
There are a number of jobs that ask for people who know specific languages and they are willing to pay well for someone who is bilingual; skills that companies wanting to reach the global market want to find.
A new way to travel
Learning Spanish when going to Spain or Mexico can allow you to travel to those areas with a different mindset. You can approach your itinerary different since you don’t have to rely on things like TripAdvisor or other similar applications.
Improving relationships
Some people have found that they are able to connect better with friends or distant family members by learning a new language. A difference in languages can cause a barrier that can be bridged when you study what they speak natively.
