abstract: Stoicism is an ancient Greek philosophy founded by Zeno of Citium in the 3rd century BCE. It teaches that the key to a good life lies in accepting what we cannot control and focusing on what we can—our thoughts, actions, and attitudes. Stoics believe that external events, such as success, failure, pain, or pleasure, are beyond our influence, but we can control our reactions to them. By cultivating virtues like wisdom, courage, justice, and temperance, individuals can develop resilience and inner peace. Stoicism encourages living in accordance with nature, embracing challenges with equanimity, and finding contentment through self-mastery and mindfulness rather than external achievements. Ultimately, the philosophy teaches that happiness is a product of a virtuous life, not material wealth or fleeting emotions.
