“When in doubt, tell the truth.”

“Never tell the truth to people who are not worthy of it.”

“When I was younger, I could remember anything, whether it had happened or not; but my faculties are decaying now and soon I shall be so I cannot remember any but the things that never happened. It is sad to go to pieces like this but we all have to do it.”

“If you have to swallow a frog, don't stare at it too long.”
