"The greatest egotism is to be constantly thinking of one's own character."

"Were there none who were discontented with what they have, the world would never reach anything better."

"The world is not a place to be happy in, but a place to do good in."

"I attribute my success to this: I never gave or took any excuse."

"I have lived, and I have loved, and I have suffered, and I have learned. And I have done what I could."
