I've been reading Five Chimneys by Olga Lengyel, a Holocaust survivor who went through the most terrible of ordeals. She became suicidal and a Frenchman who got her involved in the camp resistance told her that if there were just one reason not to do it, it was so she could do little things to make the lives of people around her better. She took this to heart and it pushed her through to eventual liberation and living till her 90s. I appreciate words are cheap, but I found this inspiring and a good way to think about life when all else seems lost.
