"I started climbing because my family is very adventurous. My life's mantra is 'limits are perceived,' so I love pushing myself to my very limit and discovering what my body and mind can do. So what better way to do it than climb the highest mountain in the world."
Prior to reaching the top of Mount Everest, the teen has already set records, becoming the youngest female to summit the 50 U.S. state highpoints last June.
