...or at least some close relative.

“For what prevents us from saying that the happy life is to have a mind that is free, lofty, fearless and steadfast - a mind that is placed beyond the reach of fear, beyond the reach of desire, that counts virtue the only good, baseness the only evil, and all else but a worthless mass of things, which come and go without increasing or diminishing the highest good, and neither subtract any part from the happy life nor add any part to it?

A man thus grounded must, whether he wills or not, necessarily be attended by constant cheerfulness and a joy that is deep and issues from deep within, since he finds delight in his own resources, and desires no joys greater than his inner joys.” ― Seneca, The Stoic Philosophy of Seneca: Essays and Letters

Abundance mentality is what this looks like to others. Attaining virtue is lifting and self improvement. Irrationality is the only evil (baseness, at least to my understanding of stoicism). All else (most women, cars, money) are a "worthless mass of things".

“And this, too, affords no small occasion for anxieties - if you are bent on assuming a pose and never reveal yourself to anyone frankly, in the fashion of many who live a false life that is all made up for show; for it is torturous to be constantly watching oneself and be fearful of being caught out of our usual role. And we are never free from concern if we think that every time anyone looks at us he is always taking-our measure; for many things happen that strip off our pretence against our will, and, though all this attention to self is successful, yet the life of those who live under a mask cannot be happy and without anxiety. But how much pleasure there is in simplicity that is pure, in itself unadorned, and veils no part of its character!{PlainDealer+} Yet even such a life as this does run some risk of scorn, if everything lies open to everybody; for there are those who disdain whatever has become too familiar. But neither does virtue run any risk of being despised when she is brought close to the eyes, and it is better to be scorned by reason of simplicity than tortured by perpetual pretence.” ― Seneca, The Stoic Philosophy of Seneca: Essays and Letters

Sounds like he's advocating against FOMO to me.

"Some things are up to us and some are not up to us. Our opinions are up to us, and our impulses, desires, aversions--in short, whatever is our own doing. Our bodies are not up to us, no are our possessions, our reputations, or our public offices, or, that is, whatever is not our own doing. The things that are up to us are by nature free, unhindered, and unimpeded; the things that are not up to us are weak, enslaved, hindered, not our own. So remember, if you think that things naturally enslaved are free or that things not your own are your own, you will be thwarted, miserable, and upset, and will blame both gods and men." --Epictetus

I think this outlook underlies or leads to many of the tenets of TRP. Abundance mentality. Outcome independence. AWALT.

I was inspired by this video from /r/stoicism(which I believe I found from a suggestion by somebody else here).
