It must not be supposed that happiness will demand many or great possessions; for self-sufficiency does not depend on excessive abundance, nor does moral conduct, and it is possible to perform noble deeds even without being ruler of land and sea: one can do virtuous acts with quite moderate resources. This may be clearly observed in experience: private citizens do not seem to be less but more given to doing virtuous actions than princes and potentates. It is sufficient then if moderate resources are forthcoming; for a life of virtuous activity will be essentially a happy life.
At the door of every happy person there should be a man with a hammer whose knock would serve as a constant reminder of the existence of unfortunate people.
The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly. There are only two mistakes one can make along the road to truth; not going all the way, and not starting.
Man falls from the pursuit of the ideal of plan living and high thinking the moment he wants to multiply his daily wants. Man's happiness really lies in contentment.
Courage is the most important of all the virtues, because without courage you can't practice any other virtue consistently. You can practice any virtue erratically, but nothing consistently without courage.
There is no denying that consideration of others is worthwhile and that our happiness is inextricably bound up with the happiness of others. There is no denying that if society suffers, we ourselves suffer, and the more our hearts and minds are afflicted with ill-will, the more miserable we become. We can reject religion, ideology, received wisdom, but we cannot escape the need for love and compassion.
When I meet people from other cultures I know that they too want happiness and do not want suffering, this allows me to see them as brothers and sisters.
The gayety of life, like the beauty and the moral worth of life, is a saving grace, which to ignore is folly, and to destroy is crime. There is no more than we need; there is barely enough to go round.
When a thoughtful human being has overcome incentives to vice and is aware of having done his bitter duty, he finds himself in a state that could be called happiness, a state of contentment and peace of mind in which virtue is its own reward.
