Please check my statement of purpose and give me a feedback..

I grew up in an environment where education was not taken seriously. No one ever stressed me to study, prepare for my exams etc.. My parents, most of my close uncles and other relatives are not very much educated. They went into business early and my parents thought of doing the same with me.
Till grade four, I studied in an ordinary school but some family friends advised my parents to change my school. So they did change my school because they also felt that my current school was not up to the mark. I was only in that school because it was nearer to my house than other schools. When I got my school changed, I went to Resource Academia in grade five. It was not until grade seven that I started to take my education seriously and for once, my parents saw the importance of education. When I was in grade seven, my father suffered a huge loss in his business and we almost got bankrupt. That was a major turning point in my life; I did not know whether my father's business would even last or not. My parents and I knew that my future was not secured and we both realized that I could not just rely on their business for the rest of life.
So I started taking education more seriously. I knew that I had to secure my future on my own. I started taking interest in my studies and excelled in it; I secured top position in computer studies in my school in 02. At that time, however, I had no aims; I did not know what I want to become in future. So I started "building up" my aims, my goals, what I want my life to be in future. I started to find myself, figured out which work I like doing the most. I had science subjects in my O and A levels and I liked doing Physics and Maths. This is the reason I took Further Maths in my A level. With these subjects I could pursue engineering as a career and I opted for electrical engineering because it is mostly Physics and Maths and also the fact that I wanted to choose a career which is well known in the world and ranks at top position. Electrical engineering fitted in all of my requirements and so I chose it as my future field.
I want to choose a career in which in which I can excel the most. Electrical engineering is one the top engineering currently and so I chose this field because I want to secure my future, I do not want to dependant on anyone, not even to my father or to his business. I want to do something unique, extraordinary in my life, in the career I have chosen, I want to start a business in future related to telecommunication and expand it all over the world. I want to make my career different from others, better from others. My aim in life is to excel in my field and let no one cross me. I want to make a name which the world can remember for a long time.
I did my O levels and got 3A*4A and 2B. I also appeared for AS level and got 2A and 1B. I also gave IELTS and got 6.5 band. Apart from my studies, I also did some extra-curricular activities in my school; I was part of the organizing committee for the school bake sale. I was also the part of the organizing committee for raising about RP 44000 in school for charity. I was also the vice house captain of yellow house and played several games. I played football and basketball matches but the game which I loved to play is cricket. I was the school cricket team captain. I lead my team in several inter-house cricket competitions. I also joined a cricket club named Cricket training programme and played for them.
Apart from school life, I also did some internships. I took part in community service; I worked in Shaukat Khanam Hospital and Bait ul Afiah trust. I had witnessed my grandfather die of gangrene and I knew how painful it was. My grandfather could not walk, all he did was to lie on his bed the whole day and the whole night. I wanted to help the old people, make their life as much better as I could because I knew what difficulties old people face. So I did an internship in the NGO "Bait ul Afiah trust." Last but not least, I worked in my father's construction company to see whether I would even like doing this work or not for the rest of my life. I figured out that the working conditions were very harsh, you had to stay under the sun for long hours, constantly walk here and there despite how hot or cold the weather is. So I did not opt for this field.
The reason I have chosen UK for my higher education is because UK has been the epitome of Higher education for decades. Universities and institutions in UK provide local and international students with quality education and exposure to the practical world which is unparallel across the world. Above all, this also entitles students with a world class degree which is accepted and reputed across the world.
