" Most of them, I suspect, come to the mall not because there is something specific that they need to buy. Rather, they come in the hope that doing so will trigger a desire for something that, before going to the mall, they didn't want. It might be a desire for a cashmere sweater, a set of socket wrenches, or the latest cell phone.
Why go out of their way to trigger desire? Because if they trigger one, they can enjoy the rush that comes when they extinguish that desire by buying its object. It is a rush, of course, that has little to do with their long-term happiness as taking a hit of heroin has to do with the long-term happiness of a heroin addict.
My ability to form desires for consumer goods seems to have atrophied.
What brought about this state of affairs? The profound realization, thanks to the practice of Stoicism, that requiring the things that those in my social circle typically crave and work hard to afford will, in the long run, make zero difference in how happy I am and will in no way contribute to my having a good life.
