My thoughts about human happiness, for some peculiar reason, had always been tinged with a certain sadness.

Men are made for happiness, and anyone who is completely happy has a right to say to himself: “I am doing God’s will on earth.

Even in Siberia there is happiness.

The happy man only feels at ease because the unhappy bear their burden in silence. Without this silence, happiness would be impossible.

“Happy as a clam, is what my mother says for happy. I am happy as a clam: hard-shelled, firmly closed.”

“Truly amazing, what people can get used to, as long as there are a few compensations.”

“Every man's happiness is his own responsibility.” 

“Folks are usually about as happy as they make their minds up to be.” 

"Happiness is a gift and the trick is not to expect it, but to delight in it when it comes."

“Action may not always bring happiness; but there is no happiness without action.

“Action may not always bring happiness; but there is no happiness without action.”

"But what is happiness except the simple harmony between a man and the life he leads?"

“A man wants to earn money in order to be happy, and his whole effort and the best of a life are devoted to the earning of that money. Happiness is forgotten; the means are taken for the end.”

“I enjoyed my own nature to the fullest, and we all know there lies happiness, although, to soothe one another mutually, we occasionally pretend to condemn such joys as selfishness.”

“For who would dare to assert that eternal happiness can compensate for a single moment’s human suffering.”

“When you have once seen the glow of happiness on the face of a beloved person, you know that a man can have no vocation but to awaken that light on the faces surrounding him”

“You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.”

“Only it takes time to be happy. A lot of time. Happiness, too, is a long patience.”

“Your success and happiness are forgiven you only if you generously consent to share them. But to be happy it is essential not to be too concerned with others. Consequently, there is no escape. Happy and judged, or absolved and wretched.”

“Call no man happy till he is dead.” 

“Happiness is a choice that requires effort at times.” 

“In the day of prosperity be joyful, but in the day of adversity consider.”

“The man who makes everything that leads to happiness depends upon himself, and not upon other men, has adopted the very best plan for living happily. This is the man of moderation, the man of manly character and of wisdom.” 

The measure of success is happiness and peace of mind.
