“What destroys a man more quickly than to work, think and feel without inner necessity, without any deep personal desire, without pleasure - as a mere automaton of duty?”

“A man without pleasure is a man without any idea what life is about”

“It was she whom I loved and whom I could not therefore see without that anxiety, without that desire for something more, which destroys in us, in the presence of the person we love, the sensation of loving.”

“A man must love a thing very much if he practices it without any hope of fame or money, but even practice it without any hope of doing it well. Such a man must love the toils of the work more than any other man can love the rewards of it.”

“What one person receives without working for, another person must work for without receiving.”

“The whole trouble lies in that people think that there are conditions excluding the necessity of love in their intercourse with man, but such conditions do not exist. Things may be treated without love; one may chop wood, make bricks, forge iron without love, but one can no more deal with people without love than one can handle bees without care.”
