Standing at 6 foot 5, Olympic gold medalist and WNBA MVP Elena Delle Donne looks like she could never be stopped.
But burnout from basketball almost ended her incredible career.
"To be honest, I burned myself out" at one point, Donne told CNBC.
It happened at the end of high school. The young athlete would get up before school to run and lift, attend a full day of school, practice after school with the team, and then train even more on her own after that.
It was too much, and the rising star nearly walked off the court for good.
"I actually gave up the game after high school and put the basketball away for a year," she said. "I started playing volleyball and set my mind to becoming an Olympian in volleyball."
While 365 days without practice would be enough to sideline most athletes, Donne came back with full force.
