Dignity is as essential to human life as water, food, and oxygen. The stubborn retention of it, even in the face of extreme physical hardship, can hold a man's soul in his body long past the point at which the body should have surrendered it.
The real things haven't changed. It is still best to be honest and truthful; to make the most of what we have; to be happy with simple pleasures; and have courage when things go wrong.
My father had taught me to be nice first, because you can always be mean later, but once you've been mean to someone, they won't believe the nice anymore. So be nice, be nice, until it's time to stop being nice, then destroy them.
