“Happy is the man who can make a living by his hobby”

“The man with toothache thinks everyone happy whose teeth are sound. The poverty stricken man makes the same mistake about the rich man.”

“The man who writes about himself and his own time is the only man who writes about all people and all time.”

“Those who do not know how to live must make a merit of dying.”

“One man that has a mind and knows it can always beat ten men who haven't and don't.”

“Doing what needs to be done may not make you happy, but it will make you great.”

“A lifetime of happiness! No man alive could bear it; it would be hell on earth.”
