Hatred, in the course of time, kills the unhappy wretch who delights in nursing it in his bosom.

Whether happy or unhappy, life is the only treasure man possesses.

Happy are those lovers who, when their senses require rest, can fall back upon the intellectual enjoyments afforded by the mind! Sweet sleep then comes, and lasts until the body has recovered its general harmony. On awaking, the senses are again active and always ready to resume their action.

My success and my misfortunes, the bright and the dark days I have gone through, everything has proved to me that in this world, either physical or moral, good comes out of evil just as well as evil comes out of good.

There is no such thing as a perfectly happy or perfectly unhappy man in the world. One has more happiness in his life and another more unhappiness, and the same circumstance may produce widely different effects on individuals of different temperaments.

I don't conquer, I submit.

When a man gets it into his head to do something, and when he exclusively occupies himself in that design, he must succeed, whatever the difficulties. That man will become Grand Vizier or Pope.
