Can somebody proofread my motivation letter?:)

Hi everybody! I'm applying for MA degree and desperately need help with my motivation letter!

Dear Sir or Madam,
I am applying for Master's Degree Program in Intercultural Studies in Communication and Administration starting in 2011.
My choice of graduate studies program is determined by a number of reason and circumstances which make mentioned above program so appealing to me. First of all I regard pursuing a degree in this field of studies will promote me both professionally and as a personality. I have been always passionate for languages, at the age of 10 I started learning English and graduated with it as my major. It fascinated me so much that by the time of my applying for undergraduate degree it was pretty clear that Foreign Languages Department was my priority. During my university studies I took part in a project initiated by one of my professors, who aimed to identify the percentage of German vocabulary in Belarusian language. The research showed that there are 3% of German words there, most of them appeared in the language long before the 20th century. This evoked my interest to the influence of neighboring cultures on Belarusian language and culture. Besides I did some research upon German proverbs and set expressions, where the purpose was to define what features of the nation do they reflect. In my Diploma thesis I had to deal with titles of English-speaking movies. The titles were grouped according to the stylistic devices used in them, and the following analysis of the groups of devices viewed some common tendencies in creating English movie-titles.
Also I was an active participant of University debate-club, took part in tournaments which were held in Minsk. My debate activities contributed a lot to my ability to hold a speech in front of the audience, to think and react immediately, to give a structured and clear response.
After the graduation I went to Germany as an Au-Pair aiming to improve my German language skills. I have spent a wonderful year there exploring the country and its culture, travelling to other European states such as France, Spain and Sweden, meeting interesting people and maturing as a personality. My host family was amazed that I adjusted so well and quick to new environment and felt at ease there. Due to my well-developed communication skills I had never had any problems abroad, besides I enjoyed helping my Au-Pair-peers in overcoming difficulties while getting used to German life-style which was a bit different from their native one. It was rather complicated for them to operate a ticket-machine at a station, the process of separate garbage collection was also quite unclear, some girls were homesick and sometimes had misunderstandings with their host families. I used to consult them in some daily routines questions, organized trips on weekends and was ready to give a helping hand when there was a need. Thus I made friends with people from different corners of the world, developed my organizational competences and proved my image of a person one can trust.
While I was a student I volunteered at Association of visually impaired people, where I did some translation work, helped by setting up cultural events and rehabilitation activities. Communication with physically different people changed my attitude to life, these people taught me to value every moment of being and not to waste opportunities that life provides me with. Despite their physical disabilities they dare to dream and take pains to make the dreams come true, they want to explore the world in the ways they can, and they struggle for being equal. After such experience it's simply shameful to say and even to think that I can't do something. I am persuaded that no dream is given without the opportunity to become a reality.
My interest in Intercultural studies is also determined by the fact that I was born and live in bilingual and multicultural country, whose authentic language and culture almost came to extinction. The recent survey revealed that only 5% of 10 million population speaks Belarusian language. It's unbelievable but people reject their own native language, considering it to be rudimentary and old-fashioned. I believe that knowledge and skills gained during the Master's studies will be very actual and applicable in my home country which is connected with other European countries both in economic and cultural spheres. Nowadays work in the field of intercultural communication in Belarus is rather slow due to certain political reasons, but also because an educational process in this direction is mostly theoretical. That is why knowledge of other cultures is limited to stereotypes. After my graduation I am intended to become a lecturer of Cross-cultural communication in a Belarusian University or ABC University. Moreover, I am interested in cultural project work and Doctoral Studies.
Furthermore the University of XYZ attracts me with its multiculturalism where I would have an opportunity to meet people from different cultural backgrounds, what is especially important regarding the specifics of the Degree program.
Thank you for your consideration, I am looking forward to receive your acceptance.
