My name is Rocio. It is my first text here, because I am new in this page. Well, I am gonna tell you about myself. As I said, my name is Rocio. I live in Argentina. Entre Rios- Parana city.I live with my parents, and my brothers and sisters. I am a student of secondary school. The next year I´ll finished the school and I think I'll study medicine or nutrition in the university. I am have been learning english since 2012, and the my reason is because I want to travel to some place from away from Argentina for exchange and meet new people, new cultures, and new ways of living because I think that the way of life here is very different to others countries. and I would like to travel around the world just because it is my dream. 
I hope I meet new people here and perfect the language! I want, too help the people who are learning Spanish.
Thank you for reading. Bye

Be careful not to make 'run-on' sentences! They can be easy to not notice, and also, make sure to select 'English' when you are saying what this was written in.
Good job!
