LESSON 4 · What Makes Us Happy?
The Paradox of Control
The Stoics divided the world into two categories: things within your control and things outside it. Your opinions, intentions, and responses — those are yours. Other people's behavior, natural events, the past — those were never yours to control. Most suffering comes from refusing to accept this division.

Epictetus, a former slave, taught that freedom is not about changing your circumstances. It is about releasing attachment to what you cannot change. A person chained to outcomes they cannot control is imprisoned regardless of their external freedom.
