At age 15, Malala Yousafzai was shot in the face by the Taliban while riding the bus from school. All because she was an activist for the education of girls in her native Pakistan.
She didn't give up.
At age 16, she addressed the United Nations. Her poise, articulateness, and charisma would be impressive for anyone, but especially remarkable for someone that young. The entire speech is inspiring, but I especially love the force of her closing, which starts at the 16:27 mark in the video.
At age 17, she is the youngest winner of the Nobel Peace Prize. Her acceptance speech is here.
(Cue the Tom Petty song.)
