“Anything you're good at contributes to happiness.”

“Liberation from the tyranny of the body contributes to greatness, but just as much to greatness in sin as to greatness in virtue.”

“It is a commonplace that happiness is not best achieved by those who seek it directly; and it would seem that the same is true of the good. In thought, at any rate, those who forget good and evil and seek only to know the facts are more likely to achieve good than those who view the world through the distorting medium of their own desires.”

“One should as a rule respect public opinion in so far as is necessary to avoid starvation and to keep out of prison, but anything that goes beyond this is voluntary submission to an unnecessary tyranny, and is likely to interfere with happiness in all kinds of ways.”

“the great world, so far as we know it from philosophy of nature, is neither good nor bad, and is not concerned to make us happy or unhappy. All such philosophies spring from self-importance, and are best corrected by a little astronomy.”

“marriage is likely to be what is called happy if niether party ever expected to get much happiness out of it”

“Dogmatism is the greatest of mental obstacles to human happiness.”
