Think of what you have rather than of what you lack. Of the things you have, select the best and then reflect how eagerly you would have sought them if you did not have them.

The most complete revenge is not to imitate the aggressor.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.

Be like the rocky headland on which the waves constantly break. It stands firm, and round it the seething waters are laid to rest.

For any particular thing, ask: What is it in itself? What is its nature?

What does not benefit the hive is no benefit to the bee.

The things you think about determine the quality of your mind. Your soul takes on the color of your thoughts.
