Receive wealth or prosperity without arrogance; and be ready to let it go.

Marcus Aurelius

He is a wise man who does not grieve for the things which he has not, but rejoices for those which he has.

Epictetus

An honest thinker will highlight and confront the most intimidating counterargument. A dishonest thinker will seek out the most ludicrous counterargument and pretend it is the only counterargument.

The Stoic Emperor

If it is not right do not do it; if it is not true do not say it.

Marcus Aurelius

Contentment comes not so much from great wealth as from few wants.

Epictetus

A gem cannot be polished without friction, nor a man perfected without trials.

Seneca
