Nothing befalls a man except what is in his nature to endure.
The best revenge is not to be like your enemy.
To the wise, life is a problem; to the fool, a solution.
Unhappy am I because this has happened to me.- Not so, but happy am I, though this has happened to me, because I continue free from pain, neither crushed by the present nor fearing the future.
A lucky chance is constant in nothing but inconstancy.
No one wearies of benefits received.
