Soldiers and athletes know from experience that the most dangerous opponent is one who lost the last contest but has the humility to learn why—and the discipline to correct their weaknesses.

The victory of each run, the victory of each race, has nothing to do with winning or losing. It has nothing to do with finishing a run or a race that truly shouldn’t be finished. It has to do with learning how to be who you honestly are, at every moment. —John Bingham
