That is happiness: to be dissolved into something completely great.
I looked on child rearing not only as a work of love and duty but as a profession that was fully as interesting and challenging as any honorable profession in the world and one that demanded the best I could bring to it.
Human happiness and moral duty are inseparably connected.
The measure of a life, after all, is not its duration, but its donation.
When we ... devote ourselves to the strict and unsparing performance of duty, ihen happiness comes of itself.
Duties are what make life most worth living. Lacking them, you are not necessary to anyone.
Seek happiness for its own sake, and you will not find it; seek for duty, and happiness will follow, as the shadow comes with the sunshine.
True happiness ... is not attained through self-gratification, but through fidelity to a worthy purpose.
The only true happiness comes from squandering ourselves for a purpose.
True happiness, we are told, consists in getting out of one's self, but the point is not only to get out; you must stay out, and to stay out, you must have some absorbing errand.
Happiness is the natural flower of duty.
The happiest excitement in life is to be convinced that one is fighting for all one is worth on behalf of some clearly seen and deeply felt good.
The secret of living is to find ... the pivot of a concept on which you can make your stand.
The only ones among you who will be really happy are those who will have sought and found how to serve.
He who never sacrificed a present to a future good, or a personal to a general one, can speak of happiness only as the blind speak of color.
The full-grown modern human being ... is conscious of touching the highest pinnacle of fulfillment... when he is consumed in the service of an idea, in the conquest of the goal pursued.
Happiness is essentially a state of going somewhere, wholeheartedly, one-directionally, without regret or reservation.
A man's happiness: to do the things proper to man.
Happy the man who knows his duties!
I believe half the unhappiness in life comes from people being afraid to go straight at things.
