Проверьте, пожалуйста!! Исправьте ошибки!) 

First of all, let me introduce myself. My name is Tanya. I am seventeen years old. I am a first year student of the Faculty of Economics
My family lives in Rostov-on-Don in one of the residential district.
I am proud of my parents and love them. I would like to spend more time with them, but they always seem to be busy. My dad has a full-time.
In my free time I go walking with my close friends or fellow students. we attend the theaters, museums, art galleries.
I receive many of emails from my friends. On the Internet, we discuss latest events, talk a lot about life, about our problems. 
But now I cant afford to spend much time for entertainment. I'm very busy
I usually spend my evenings at home. I read, do my homework, study English. English is a very difficult language. But I hope to master it because it is useful to me in the future. I try to be a diligent and bright student.
I enjoy learning, but I get tired after class, and I feel a headache.
I want to travel to different countries, but unfortunately I do not have this opportunity now.
And the last thing I would like to tell you about things I hope to achieve in my life are: finishing the University, to have a very successful career, to build the home of my dreams and to find someone in my life to share all that with.
