“So long as one is happy one can endure any discipline: it was unhappiness that broke down the habits of work.”

“Endurance is one of the most difficult disciplines, but it is the one who endures that the final victory comes.”

“All happy families resemble one another, but each unhappy family is unhappy in its own way, and when it comes to the Holiday Season, happy families can abruptly become unhappy and unhappy families can, to their great alarm, be happy”

“Habit is necessary. It is the habit of having habits, of turning a trail into a rut, that must be incessantly fought against if one is to remain alive ... one can remain alive long past the usual date of disintegration if one is unafraid of change, insatiable in intellectual curiosity, interested in the big things, and happy in small ways.”

“One's emotions are intensified in Paris—one can be more happy and also more unhappy here than in any other place. But it is always a positive source of joy to live here, and there is nobody so miserable as a Parisian in exile from his town.”

“Habit is habit, and not to be flung out of the window by any man, but coaxed down-stairs one step at a time.”
