On my sixteenth birthday, I came home carrying the first gold medal anyone in my family had ever won.

It was October 14, 2011, in Columbus, Ohio.

I had spent three years training for the statewide high-school swimming championship. Every morning, I woke at 4:45 before school, took two buses to the aquatic center, and worked weekend shifts at a grocery store to pay for equipment my parents called “too expensive for a hobby.”
