Hill was 15 when it all came to a head. He and a friend snuck out one night in an SUV. Hill stuck his elbow out the open window as they headed into the night, and his friend started turning the wheel back and forth, joking around. The car flipped over, skidded along the road and dragged Hill's arm with it.
Hill woke up in the hospital, and he heard two doctors discussing whether or not to amputate his arm. At the same time, he saw his dad and ailing mom crying. "I said to myself, 'I'll never let them down ever again.' I said, 'I'm going to be f*ckin' successful. I'm going to resurrect what I put these people through by being a little a**hole.' So I look at this scar every day. That reminds me to work hard."
