Epictetus

Epictetus was an ancient Greek Stoic philosopher who taught that our happiness depends on how we respond to life's events, rather than external circumstances. He emphasized focusing on what we can control—our thoughts, choices, and attitudes—and accepting what we cannot change. His teachings encourage resilience, self-discipline, and inner tranquility by cultivating virtue and wisdom. Despite being born a slave, Epictetus became a respected teacher whose ideas continue to influence modern philosophy and personal development.
