I am motivated by the idea of helping thousands of people annually. I love to help a person in need. It makes me feel better as a person.
This is a nice theme, Courtney.
I want to tell you that it is important to write in paragraphs instead of just using one paragraph. If you have more than a few sentences, use at least 2 paragraphs. It helps the reader to think clearly about the theme.
What I see in this essay is an assertion that you are a serious student dedicated to helping others. BUT I think you can show something more. Read some articles about anesthesiology and recent developments related to your interests... and read about philosophy of nursing. Read some articles, and let your essay show that you are interested in current topics in the field. It's easy and interesting! :-)
