Undergraduate / I am a hard working person and never take rest until my work is done [5]

I am having a hard time in starting my Personal Statement

I am a business administration's undergraduate student. I am applying for a foreign program and I need to answer these questions and I am totally blank at this stage

o Your goals in terms of your field of study and personal development, and
o The reasons why you wish to pursue them in the U.S.A. and type of program you hope to pursue and how it relates to your interests and future objectives.

I want some tips, starters of sentences so that my mind will start working..

About me, The ultimate goal is to achieve something big in life; which has fascinated me since childhood. I am a hard working person and never take rest until my work is done. I am dedicated towards studies and a scholarship holder too. I am a simple girl living with high hopes and big dreams. I want to pursue my career in U.S, because I love that country for so many reasons. Related to my field, I would love to see how people from different backgrounds and races lives and work together.

Can you provide some other valid reasons that why would someone likely to pursue their career in U.S? How would I go with personal development? I would be going for MBA after graduation but how to pen them down in a smart way?

P.S My text is looking very perplexed. Isn't it? Please help :(
