I have never let my schooling interfere with my education. - Mark Twain

"Humor is mankind's greatest blessing."

"I've had a lot of worries in my life, most of which never happened."

"The trouble is not in dying for a friend, but in finding a friend worth dying for."

"Lord save us all from old age and broken health and a hope tree that has lost the faculty of putting out blossoms."

"A clear conscience is the sure sign of a bad memory."
