Life without the courage for death is slavery.
No man is more unhappy than he who never faces adversity. For he is not permitted to prove himself.
Let him who has given a favor be silent; let he who has received it tell it.

If you live according to nature, you never will be poor; if according to the world's caprice, you will never be rich.
Beauty is such a fleeting blossom, how can wisdom rely upon its momentary delight?
