I will make an attempt to help you with this. My advice may not be comprehensive but I hope it will be useful.
I will show my corrections in red to help focus you and my general advice in blue.
First of all though, I understand that Arabic is written aligned to the right. English (and all western languages) are written aligned to the left.
When I was a little girl, my Mother told me she thought that I was clever. She said "Oh, my lovely daughter, you are so very clever. I think, if you study hard, you could become a doctor someday!"
I accepted this idea and, gradually, I came to believe I could achieve it. I told all of my friends that some day, I would become a doctor.
My dream stayed with me until I started intermediate school. By the time I progressed to secondary school, the dream had disappeared altogether until, two years ago, I decided that I wanted to study to become a translator. I enjoyed studying languages and wanted to earn my living as a professional translator.
Translation is very difficult and challenging to learn. There are many grades and styles of translating. Although it is very hard, I believe I am capable of achieving this and I am determined to succeed. I have worked very hard to realise this dream.
I have so far completed three courses in my english studies at my university and I have transferred to the english department. I do additional studies to help develop my skills and abilities in learning english. I use the resources available on the internet and I have become a moderator on one of the websites that I frequent. I spend my time helping other students of differing abilities by providing them with resources that have helped me in my own studies such as stories and essays and resources such as dictionaries and games.
Learning and studying english has been very fulfilling for me and has made a big difference to my life and my outlook.
I give my thanks and praise to Allah (PBUH) for his kindness, wisdom and guidance and I humbly ask that he continue to grant my dreams.
I hope this has been helpful and I hope my critique hasn't felt too harsh to you. There are some other odds and ends (such as capitalising the word 'english' perhaps that others may comment on). I would stress that, however much you might feel you have to do, you have made yourself quite understood here, so you can be confident that you english is of a very good standard. We all (not least myself!) have more to learn.
Thanks and best of luck to you!
