“The bond between a man and his profession is similar to that which ties him to his country; it is just as complex, often ambivalent, and in general it is understood completely only when it is broken: by exile or emigration in the case of one's country, by retirement in the case of a trade or profession.”

“I hold every man a debtor to his profession.”

“The trouble with specialists is that they tend to think in grooves.”

“Professionalism is knowing how to do it, when to do it, and doing it.”

“Those who trust us educate us.”

“Nothing is so good as it seems beforehand.”

“What loneliness is more lonely than distrust?”

“One must be poor to know the luxury of giving.”

“It is never too late to be what you might have been.”

“The strongest principle of growth lies in human choice.”
