Stoics differ in which aspect of the practice of Stoicism they find to be most challenging. Some might find it hardest, for example, to stop dwelling on the past; others might find it hardest to overcome their lust for fame and fortune. The biggest obstacle to Marcus’s practice of Stoicism, though, appears to have been his rather intense dislike of humanity. Indeed, throughout the Meditations, Marcus makes it abundantly clear how little he thinks of his fellow man.
