When a person finds themselves predisposed to complaining about how little they are regarded by others, let them reflect how little they have contributed to the happiness of others.

To hear complaints is tiresome to the miserable and the happy.

When any anxiety or gloom of the mind takes hold of you, make it a rule not to publish it by complaining; but exert yourselves to hide it, and by endeavoring to hide it you drive it away.

The true sound and strong mind is the one that can embrace equally great and small things.

Our minds should not be empty because if they are not preoccupied by good, evil will break in upon them.

Laws teach us to know when we commit injury and when we suffer it.
