“People with a grudge against the world are always dangerous. They seem to think life owes them something. I've known many an invalid who has suffered worse and been cut off from life much more . . . and they've managed to lead happy contented lives. It's what's in yourself that makes you happy or unhappy.”

“It is a curious thought, but it is only when you see people looking ridiculous that you realize just how much you love them.”

“I like living. I have sometimes been wildly, despairingly, acutely miserable, racked with sorrow; but through it all I still know quite certainly that just to be alive is a grand thing.”
