The Stoics tended to view joy not as the goal of life, which is wisdom, but as a by-product of it
Nobody has ever had the words “I wish I’d watched more television” or “I wish I’d spent more time on Facebook” engraved on their tombstone.
Joy in the Stoic sense is fundamentally active rather than passive; it comes from perceiving the virtuous quality of our own deeds, the things we do, whereas bodily pleasures arise from experiences that happen to us, even if they’re a consequence of actions like eating, drinking, or having sex.

Stoicism teaches the development of self-control and fortitude as a means of overcoming destructive emotions; the philosophy holds that becoming a clear and unbiased thinker allows one to understand the universal reason (logos). Stoicism's primary aspect involves improving the individual's ethical and moral well-being: "Virtue consists in a will that is in agreement with Nature."[11] This principle also applies to the realm of interpersonal relationships; "to be free from anger, envy, and jealousy,"[12] and to accept even slaves as "equals of other men, because all men alike are products of nature".[13]

Begin the morning by saying to yourself, I shall meet with the busy-body, the ungrateful, arrogant, deceitful, envious, unsocial, Marcus Aurelius
