Robert A. HeinleinVictory in defeat, there is none higher. She didn't give up, Ben; she's still trying to lift that stone after it has crushed her. She's a father working while cancer eats away his insides, to bring home one more pay check. She's a twelve-year-old trying to mother her brothers and sisters because mama had to go to Heaven. She's a switchboard operator sticking to her post while smoke chokes her and fire cuts off her escape. She's all the unsung heroes who couldn't make it but never quit.
