“I am happy that I can aid those admirable men, both living and dead, who by their pens or their tongues have aided the great cause of human liberty and universal happiness.”

“When a man says to me, 'Let us work together in the great cause you have undertaken, and let me be your companion and aid, for I admire you more than I have ever admired any other woman,' then I shall say, 'I am yours truly'; but he must ask me to be his equal, not his slave.”

“Happiness is for those who don't really need it. So I can live without happiness.”

“There are two godheads: the world and my independent I. I am either happy or unhappy, that is all. It can be said: good or evil do not exist. A man who is happy must have no fear. Not even in the face of death. Only a man who lives not in time but in the present is happy.”

“Over the course of my years, I have met thousands of people. I have dined with the prosperous as well as the poverty-stricken. I have conversed with the mighty and with the meek. I have walked with the famous and the feeble. I have run with outstanding athletes and those who are not athletically inclined. One thing I can tell you with certainty is this: You cannot predict happiness by the amount of money, fame, or power a person has. External conditions do not necessarily make a person happy… The fact is that the external things so valued by the world are often the cause of a great deal of misery in the world. Those who live in thanksgiving daily, however, are usually among the world’s happiest people. And they make others happy as well.”

“I don’t need a hearing aid—I need a listening aid. And this aid, she’d better be pleasing to look at.”
