Stoicism is an ancient philosophy that teaches the development of self-control and resilience as a means to overcome life's challenges. Founded in Athens by Zeno of Citium, it emphasizes the importance of focusing on what we can control while accepting what we cannot. Stoics believe that our thoughts and reactions shape our experiences, encouraging us to cultivate a mindset of inner peace and rationality. At its core, Stoicism promotes virtues like wisdom, courage, justice, and temperance. Famous Stoics like Marcus Aurelius and Seneca wrote extensively about how to live a good life, reminding us that true happiness comes from within, not from external circumstances.
