Most of what Morgan Housel talks about in his Psychology of Money are principles that stoic philosophers would advocate for long back in the ancient times.
Compounding vs confounding for example closely matches the virtue of temperance. According to Morgan, it's quintessential to play the game of investments for the longest period possible. This requires staying calm in times when the world collapses into chaos, which is the central aspect of the virtue of temperance.
In his On the shortness of life, Seneca talks extensively on the importance of keeping your guards up at all times, of not letting transient success to stir you up into unreasonable confidence:
"She [Fortune] falls heavily on those to whom she is unexlected; the man who is always expecting her easily withdtands her."
This same idea is covered in chapter 5 on Getting wealthy vs Staying wealthy:
"It [keeping money] requires humility and fear that what you've made can be taken away from you just as fast. It requires frugality and an acceptance that at least some of what you have made is attributable to luck, so past success can't be relied upon to repeat indefinitely."
Chapter 3 - Never enough talks about the inherently greedy temperament of humanity. It states that regardless of how unimaginably high some people haven't climbed up the wealth ladder, they would want more and more and more, and that would eventually usher their own demise.
In Letters form a stoic, Seneca emphasizes, "It is not a man who has too little, but the man who craves more, that is poor."
In his Discourses, Epictetus shares an identical sentiment:
"Wealth consists not in having great possessions, but in having few wants."
And, lastly, I'd also consider it apt to quote Marcus Aurelius:
"Very little is needed to make a happy life; it is all within yourself, in your way of thinking."
As I continue on the book, I keep seeing the same pattern over and over again: although history doesn't exactly repeat itself, human nature does. Therefore, the fundamental principles for living in human society have always stayed the same, irrespective of how advanced the civilization has got. It's good to take a glance back at what happened back then and see if the pattern is relatable and if the game plan can still be applied.
