Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth.

— Marcus Aurelius

Observe always that everything is the result of change, and get used to thinking that there is nothing Nature loves so well as to change existing forms and make new ones like them.

— Marcus Aurelius

Just keep in mind: the more we value things outside our control, the less control we have.

— Epictetus

Let us prepare our minds as if we’d come to the very end of life. Let us postpone nothing. Let us balance life’s books each day. The one who puts the finishing touches on their life each day is never short of time.

— Seneca

The art of living well and the art of dying well are one.

— Epicurus
