I have a saying that I thought of a few years back after watching the movie and reading the book, The Road.
In the story, a father treks his way with his young son through post- apocalyptic America.The father will do anything to help his son survive. He gives up the last bite of food to his son. He protects him from people who are trying to eat him for god's sake. Quite simply, the father always has "one more(rep) for the apocalypse", no matter what. I shortened it to "One for the Apocalypse", and it stuck with the folks that I train. It means that you ALWAYS have one more in you, one more sprint, one more squat..always one more if it is really important .Hell, if your life or a loved one's life is in danger, you could fight a little more couldn't you? And there it is- "One More for the Apocalypse"
