Someone once described them self as a narcissist to me. So, I guess when a too short and unsatisfying article from huffpo came across my timeline, it piqued my interest. In economics, I think I associate this with “rational self-interest calculator”.
p.s. after reading the article all the way through, I don’t really feel satiated, but, well, it is what it is, as the saying goes. The original huffpo article’s expert said something about setting boundaries, or “deal-breakers”, as he put it.
