I have spent many years in the sciences: laboratory research, clinical research, various internships and volunteer experiences. All this plus my extracurricular involvements have come together in my pursuit of a career in medicine for an urban underserved population. But any Pomona student knows that a person is more than just their work: my professional interests and ambitions have a background story, as do all the other aspects of my life. Ask me about these things, but you can also talk to me about my travel adventures, the book I'm currently reading, my Christian faith, etc.
And my advice to you is the same: You are more than your studies. Don't confine yourself to the pages of a textbook or the walls of a classroom; the world is so much bigger. And regardless of what I or anyone else can tell you, it will never beat you discovering and experiencing it for yourself.
