There is no need to mention your father's kidney transplant as it does not relate to anything about the way he influenced you as a person. Your essay should be focused on the overall effect of the community, your family, and your academics on the development of the person you are today. Try not to use cliche statements like
whenever life throws you a curve ball, face it with a smile on your face
Rather, show us how you learned that you should face life challenges with a smile from your father. Then show us how your mother taught you about the importance of balancing things in your life. I also think that you should reconsider what you have now as your closing sentence.
The world I come from has taught me to be hard working, perseverant and to always strive for excellence. It has made me realize that I alone am the master of my fate.
is such a powerful statement to be making towards the end of the essay. The impact upon the reader is wasted. Please consider making this your opening sentence instead. I believe it will have the fullest effect on your written work once placed in that position.
