Help finishing my motivation letter plzzzz

Please help me to finish my motivation letter, please check the following part.

The last 10 years in more details:
Unfortunately after secondary school i was not allowed to choose what i want to study, the ministry of education gave every student 3 choices and each student had to choose one of them, unfortunately engineering wasn't one of these choices.

I choose for science so i subscribed in the Faculty of Science Milan university.
After 4 years "in the year 2000" when i was in my third year i quited for personal reasons and i started work and start have some company courses (marketing, management and computers) after that i start work in the marketing department of el xxxx "www.xxxxx.com.

I worked for this company until summer 2003 then we decided to goto Sweden.

One of the reasons that i left my job and traveled to Sweden is that there was a possibility to continue what i was always dreaming of, but i couldn't start immediately so i have started learning the language of the country first then i had to work, so i decided to work for a couple of years to save some money that can help me to do full time studies, but in the mean time i did the information technology course, and now I'm really ready for the new beginning and for full time studding.

In my last year in information technology, and because me and 2 other colleagues were very interested in electronics and (MMI) man–machine interaction, our final project was about creating an application that will monitor and control power supplies located in 650 place in Sweden remotely. in order to to finish this project, we had to study some electronics and machines subjects with a help from Eng. "Snyler Cheroke" and from Eng. Marc Astrid, they gave us some tasks to fully understand how the machines "power supplies" are working so we can reach our goal and create the application.
Fortunately we had a great success. The application works good and it's in the testing phase at the moment, and hopefully they will run it somewhere at the end of this year.

finally i would like to mention that, for me mathematics, physics, chemic, programing ...etc are not just some subjects that i have to study but i really enjoy learning these subjects because they represent a challenge for me and i love challenge because challenge is fun, and I'm sure that I will be good in these subjects.


Thx in advance
