To honor the amazing things girls across the country, Seventeen magazine launched their second annual "Pretty Amazing" Contest with the goal of finding a girl who's making an impact in her community and inspiring others to do the same. When the essay contest opened earlier this year, entries poured in by the thousands.

Last year's winner, Zoë Damacela, went from living on the streets to creating and selling her custom fashion designs to put herself through college. And this year's batch is no less impressive. One finalist is passionate about raising support for LGBTQ teens, while another is chasing her ballerina dreams. Click through the slideshow below to meet the five pretty amazing girls.
