Dress not thy thoughts in too fine a raiment. And be not a man of superfluous words or superfluous deeds.

Observe the movements of the stars as if you were running their courses with them, and let your mind constantly dwell on the changes of the elements into each other. Such imaginings wash away the filth of life on the ground.

Receive the gifts of fortune without pride, and part with them without reluctance.

Accustom yourself not to be disregarding of what someone else has to say: as far as possible enter into the mind of the speaker.

All is as thinking makes it so

He who follows reason in all things is both tranquil and active at the same time, and also cheerful and collected.

I am an old man and have had many worries, but most have never come to pass.
