Sophocles

It is a painful thing to look at your own trouble and know that you yourself and no one else has made it.

The greatest griefs are those we cause ourselves.

What fate can be worse than to know we have no one but ourselves to blame for our misfortunes!

All is disgust when one leaves his own nature and does things that misfit it.

Why should a man fear since chance is all in all for him and he can clearly fore-know nothing? Best to live lightly as one can unthinking.

Seize the hour.

Chance never helps those who do not help themselves.

One word frees us of all the weight and pain of life: That word is love.

Kindness gives birth to kindness.

Whom Jupiter would destroy he first drives mad.

One learns by doing the thing for though you think you know it you have no certainty until you try.

Best to live lightly unthinkingly.

Wisdom is the most important part of happiness.

Our happiness depends on wisdom all the way.

When a man has lost all happiness he's not alive. Call him a breathing corpse.

To throw away an honest friend is as it were to throw your life away.

Rather throw away that which is dearest to you your own life than turn away a good friend.

You win the victory when you yield to friends.
