“The happiness of your life depends upon the quality of your thoughts.”

“Very little is needed to make a happy life; it is all within yourself in your way of thinking.”

“The happiness of those who want to be popular depends on others; the happiness of those who seek pleasure fluctuates with moods outside their control; but the happiness of the wise grows out of their own free acts.”

“Do every act of your life as though it were the very last act of your life.”

“Do every act of your life as if it were your last.”

“Whenever you want to cheer yourself up, consider the good qualities of your companions, for example, the energy of one, the modesty of another, the generosity of yet another, and some other quality of another; for nothing cheers the heart as much as the images of excellence reflected in the character of our companions, all brought before us as fully as possible. Therefore, keep these images ready at hand.”

“Remember that very little is needed to make a happy life.”
