This takes me back to a scene in the movie, When the Game Stands Tall, where a high school football player is pacing a wounded warrior on a treadmill. It turns into a contest of endurance and the highschooler quits stating the vet could go on forever. The vet then replies, “No. Not forever Danny, just a little more than you.” If we stop when we get tired, we will never get to our finish lines.
