I want to learn English

Hi, everyone! I want to learn a new language, but I don't know how to start. I want to improve my English, because I like to communicate with people. I love people. I want to see the world and get to know different cultures. I believe that life will be beautiful.

Notes:

There are really only minor errors in your entry. As a rule, you'll want to be sure that English and any other names of languages you use are capitalized. Other than that, I just changed some things to make your passage sound more natural. For example, "to advance my English" isn't incorrect, but it does sound unusual. "To improve" makes for a better sounding sentence here.

I hope this helped! Please let me know if you have any questions!
