Meditations is what immediately came to my mind also. It's a humbling and reassuring look into the mind of a great leader and stoic; to know that there was this man, the most powerful in his time, who strived - and struggled - to be the best he could, is inspiring.
Are we really going that low to take beliefs from WER (white, educated, rich) people? I mean wasn't Seneca the rich man during that time? And also Marcus Aurelius book doesn't seem appealing to read because it was never meant to be published.
About the 'white' part: the Roman empire apparently did not categorize people based on something as superficial as their skin color: "physiognomy did not function as a criterion of social status in the Roman system of stratification". [1]
