Graduate / Drawing a blank on Essay prompt (is there an outline?) [4]

Hello

For one of my business school essays, I have to answer the question "Why do you want to pursue this graduate program at ____________? and I really do not know how to start or end this essay. Is there any outline I can follow

I know I want to go to the school because it has a stellar reputation in my concentration area, and I need a change of environment but I can say all these in a paragraph!

Help!!!!

Undergraduate / Background, interests, personal and professional accomplishments [5]

Thank you so much for your input! I definitely feel like I can put something together now for that essay.
I have 7 essays to write so I am kind of all over the place!

Please can I get some feedback for this essay that I put together. I think the first paragraph is a bit too long, and I also need some suggestions on how to conclude.

P.S I am not a native English speaker so some of my wordings might be different.

Describe your background, interests, personal and professional accomplishments, and how they demonstrate your potential for success in this degree and your career

Waking up every morning and going to school was burdensome for me while in secondary school,I was labeled by several teachers as a child with potential. The problem was that I had no drive or motivation so I continuously wondered what others saw in me. I managed to finish secondary school with above average grades knowing it was not my best effort. However my life changed forever when my sister who was in college in the United States went missing the summer right after I finished secondary school. She had been missing for a week, and people around me started giving up hope. While wondering around the house dazed one day, I overhead someone making a comment about how it was such a pity that my sister who was exceedingly bright and whom who my younger brother and I looked up to was gone leaving me as the older sister to which my younger brother would look up to and what a poor example my brother had to look up to. This comment made my chest heavy with a feeling that cannot be put into words and I made up my mind to change everyone's mind. My sister was found later on that summer thankfully, but someone had unknowingly made me passionate about something for albeit the wrong reasons and changed the rest of my life.

I started college at _____________and studied hard in order to prove that I could work hard and be looked up to. I finished my first semester of college with a 4.0 GPA and I was proud of myself and felt like I had proven a point. Gradually, my mind set changed, and it became less about proving to people that I was responsible or good enough to be looked up to and more about the personal delectation I derived both from learning and the rewards of hard work. I continued to put in my best in my academic studies with a couple of trials and bumps on the way but I had overcome the biggest bump of them all which was myself so the others seemed insignificant in comparison. Over the course of my undergraduate studies I garnered several awards and scholarship including the Outstanding Undergraduate Student in Finance, _______International Ambassador and being one of only 8 students inducted into Beta Gamma Sigma- the academic honors society for business students at my school in the year 2008. All these accomplishments have shown me one thing; which is that with persistence, determination and hard work I am capable of achieving anything I set my mind to do.

I intend to face the masters program in Management Information Systems at Mays Business School and my career with this same mindset.... ....
