Waste no more time arguing about what a good man should be. Be one.

This quote, often attributed to Marcus Aurelius, encapsulates a Stoic philosophy that emphasizes practical virtue 

and action over theoretical debates. Let's break down the meaning of the quote: 

"Waste no more time arguing about what a good man should be.":   This part of the quote 

suggests that engaging in prolonged debates or discussions about the abstract qualities

and characteristics of a virtuous person is not productive. It implies that theoretical arguments  

about morality and goodness might be intellectually stimulating but could 

be a diversion from the more important aspect of living a virtuous life.  

"Be one.": The crux of the quote lies in this succinct directive. Instead of spending time debating virtues, 

Marcus Aurelius advises that the focus should be on embodying those virtues in one's own life.
