Wow. This was honestly better with than I think most native speakers could manage. A few grammar errors which give it away that you are not perfectly fluent but I am so impressed with your vocabulary.

Let me know if you have any questions about the corrections I made and I can explain the technical reasons for the changes. 

Learning foreign languages is a waste of time and money

We live in time of globalization when knowledge of several languages is very valuable. Nevertheless, some people believe that learning languages is useless.

In my opinion, learning foreign languages is an investment in the future. Firstly, having language skills gives you advantages when you get a job. You become a more skillful employee and can get a well-paying, interesting job. Secondly, it expands your mind as you learn about different cultures and traditions. Finally, you can use foreign languages while traveling. For example you can communicate with foreigners, you will never get lost, and you will be able to place an order in a restaurant or book a room in a hotel.

However, a lot of people consider learning foreign languages meaningless. They think that it is rather expensive and it may be useless in the future because you may never have an opportunity to use it.

Personally, I do not agree with this point of view, because there are lots of cheap ways of studying a new language. You can, for example, use the Internet to communicate with native speakers, read foreign books, and listen to audiobooks to improve your language skills. Moreover, you can use a new language while staying in your own country. For example while doing your job, translating lovely a song or watching foreign movies.

In conclusion, I want to stress that learning foreign languages is very useful as it can help you to live in the modern world and to be a successful and developed person.
