Seneca
Difficulties strengthen the mind, as well as labor does the body.
Our plans miscarry because they have no aim. When a man does not know what harbor he is making for, no wind is the right wind.
He who has great power should use it lightly.
It is not because things are difficult that we do not dare, it is because we do not dare that they are difficult.
Wherever there is a human being, there is an opportunity for kindness.
It is impossible to imagine anything which better becomes a ruler than mercy.
It is not the man who has too little, but the man who craves more, that is poor.
Sometimes even to live is an act of courage.
