Scholarship essay ..can anyone help !

Hi guys , this is my first time posting in here .I'm in a program that prepares international high school students to apply for american universities .So i'm supposed to write a 500 words to :
Explain my financial situation and convince the committee that i'm a good condidate for the scholarship.
Describe how will studying in the USA will help me achieve my goals .
So if you could read it and tell me what you think :
‘Let’s address the choices we may have not necessary to choose one right now but to prepare to live these choices in a way that looking backwards someday we will not regret it and we will be capable of making new choice and we will still think that our life is fascinating’ this is a quote that I took a year ago from a movie called: Mr. nobody. A story that changed my pure image of the world, it shook up my pink concept of life. It made me realize that life is too short to make the wrong choices and once you've made one you won’t be able to come back on it.

I’ve lived all my little life in the same little city in a little quite family .We were four kids and Despite not going to universities or earning high degrees my parents gave us the gift of intelligence. We grew up in an academic and an open minded environment my Father was a contractor and my Mother was a high school principal but she left her job to raise us. I played Judo, soccer and Swimming.Growing up things started to get a little tougher as my sisters got into med school and my brother into the hydrocarbon and chemistry institute.

I want to be a computer engineer and because of my wide range of interests and passions I would like to immerse myself in another culture and deepen my personal and academic understandings. I envision for myself a career straddling the highest levels of the high-technology industry. I wouldn't be too cocky if I dreamed of Studying at MIT (Massachusetts Institute of Technology) or working side to side with Bill Gates or Steve Jobs because as David Starr Jordan said ‘Wisdom is knowing what to do next skill is knowing how to do it and virtue is doing it’. And I believe that I have been wise enough to know what to do next, the *** is building my skills and showing me how to do it and the American education will help me reach the enough virtue to do it.

So here I’m today, convinced that I’m doing the right thing, I made the right choice: I want to study in the U.S.A. No matter how hard it seems or how impossible it may look I’m willing to go beyond my limits, explore all my potential to achieve my goals. First of all, because the American universities are constantly very high in world rankings and they offer top-notch education programs with highly qualified teaching staff . In the other hand, Studying is the U.S.A offers an endless study choice which gives international students various possibilities .Plus, America is a melting pot of people from all over the world. One will find most Americans to be very hospitable, friendly, kind, generous and accepting of foreigners.

That why I want to study in the U.S.A and be part of that environment to improve my existence and who knows maybe one day the world’s.
