Stoic joy is characterized by a deep sense of fulfillment derived from living with purpose, striving for excellence, and fulfilling one's duties. Unlike fleeting feelings of happiness represented by a smile, this joy is rooted in seriousness and commitment. It emphasizes a substantial approach to life rather than superficial expressions of cheerfulness.
This perspective aligns with the teachings found in "The Daily Stoic" by Ryan Holiday, which features insights from ancient philosophers like Seneca, Epictetus, and Marcus Aurelius. The book encourages readers to cultivate a joy that comes from inner strength and virtue, highlighting the importance of living with intention and responsibility.
