Seneca The Younger

Those that are a friend to themselves are sure to be a friend to all.

It is medicine, not scenery, for which a sick man must go searching.

To strive with an equal is dangerous; with a superior, mad; with an inferior, degrading.

No man ever became wise by chance.

Laugh at your problems; everybody else does.

That grief is light which can take counsel.

The spirit in which a thing is given determines that in which the debt is acknowledged; it's the intention, not the face-value of the gift, that's weighed.

I had rather never receive a kindness than never bestow one.

You need a change of soul rather than a change of climate.

No man is more unhappy than he who never faces adversity. For he is not permitted to prove himself.

True praise comes often even to the lowly; false praise only to the strong.

No evil is without its compensation. The less money, the less trouble; the less favor, the less envy. Even in those cases which put us out of wits, it is not the loss itself, but the estimate of the loss that troubles us.

Just as so many rivers, so many showers of rain from above, so many medicinal springs do not alter the taste of the sea, so the pressure of adversity does not affect the mind of the brave man. For it maintains its balance, and over all that happens it throws its own complexion, because it is more powerful than external circumstances.

The artist finds a greater pleasure in painting than in having completed the picture.

He is a king who fears nothing, he is a king who desires nothing!

I will govern my life and thoughts as if the whole world were to see the one and read the other, for what does it signify to make anything a secret to my neighbor, when to God, who is the searcher of our hearts, all our privacies are open?
