“Contemplation often makes life miserable. We should act more, think less, and stop watching ourselves live.”

“Don't you know that we must always have a place where we never go but where we think we'd be happy if we did?”

“We ought to be able to combine opposites: the love of goodness with indifference to other people's opinions, a liking for work with indifference to fame, concern for our health with indifference to life.”

“In order not to find life unbearable, you must accept two things: the ravages of time and the injustices of man.”

“Ce que j'ai appris, je l'ai oublié ; ce que je sais, je l'ai inventé.”

“The most wasted of all days is one without laughter.”

“A day without laughter is a day wasted.”
