Hi eveyone

I'm applying for bsc Economics in the UK . Could someone check the motivation letter for me please?
Dear Sir or Madam,
I am writing to apply for the BSc Economics course at Your University.
Currently I am studying at a technical school for economics in Hungary. I participated in a preparatory language course in the first year where I started to study English and German,( so I speak both languages quite well.) I will graduate in 2016.
When I was 15 and started hight school,I was lost because I did not know whether I made the right choice to study economics or not. First, it was really hard for me to adapt to the new tasks which required a totally different thinking from what I had known . But as the time passed the tasks became something more. They were not only numbers,equations and diagrams anymore , they were rather beautiful systems which finally form a !!!!. I realised that it is the reason behind almost every decision in our lives, whether it is as small-scale as a shopping trip or as big as an international structure. In this way it provides a general understanding of how the world works. I would like to experience this world not just by seeing it, but being completely part of it. Along with this, I would like to aggravate my studies in international relations and national markets. It is something that keeps changing depending on the current situation, which is perfect for someone like me, who is interested in development and studies ,which apply to our world and current issues.
My time spent abroad taking part in draughts championships, really opened my mind and taught me, there are still lots of beautiful things to discover, by travelling, studying and meeting new people. It helped me to be open-minded about different cultures. That experience was something I wanted to get more of it so I decided to host an exchange student. While she was with us, we grew into a family and created an international friendship that lasts a lifetime. I learned how to interact with people with totally different ideas, which in fact gave me a better understanding of the differences between cultures. It was only after she left when I noticed that I even started to see the world differently. I began to understand the value that people embody.
As a member of the Student Council, I helped organizing school activities for students which developed my organization skills and I learned how to be a full member of a team.
I am eager to gain new experiences and in my opinion programme of Your University is the best way to achieve all of it and to explore the uniqueness of the industry. Its international aspect and very high standard of education encounters different students from various countries, so the interaction during the study is very enriching and exactly what I am looking for. I am positive that Your University is an excellent start for an ambitious career.
Thank you for considering my application
Sincerely yours
