Finishing races are​ important, but racing is more important – said Dale Earnhardt. 

He was part of a group at the Devil’s circuit and he was the only one to finish all the 15 obstacles. When I asked him how he managed at his age,  he said, he conquered one obstacle at a time and enjoyed the experience. His aim was to conquer all of them which he did. Life lesson - come, see, conquer - one obstacle at a time.
