A person with a new idea is a crank until the idea succeeds. - Mark Twain

"When we remember we are all mad, the mysteries disappear and life stands explained."

"I have never let my schooling interfere with my education."

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

"Familiarity breeds contempt and children."

"Good friends, good books, and a sleepy conscience: this is the ideal life."
