Do not indulge in dreams of having what you have not, but reckon up the chief of the blessings you do possess, and then thankfully remember how you would crave for them if they were not yours.

Marcus Aurelius (121–180 CE) was a Roman emperor and Stoic philosopher known for his posthumously titled work, Meditations. Assumed to have been written for his own self-improvement, the book examines life experiences through the lens of Stoic principles, which emphasize living virtuously, rationally, simply, and with full responsibility for one’s actions and obligations.
