Stoicism is not just a tool for staving off unhappiness when we don’t get a much-desired promotion—it also teaches us to put that promotion and all our success in its proper perspective.

As Seneca said, “Once we have driven away all that excites or affrights us, there ensues unbroken tranquility and enduring freedom.”
