It's a philosophy for and by the wealthy who aspire to act less opulently. Stoicism is appealing because it is a philosophy for and by the wealthy (e.g., Cicero, Marcus Aurelius, Seneca) who wished to conduct more appropriately. That wasn't too shabby. Nowadays, however, it entails the axiom: be wealthy first, then good. That isn't very inspiring. Stoicism is attractive because it provides a clear framework within which to organize one's life. It isn't that hard to do. You just need to know where to look. For example, you should live each day as if it were your last, because you never know when that will be. Also, don't be attached to anything external to yourself; separate yourself from others' misfortunes; avoid disturbance and anxiety; show courage in face of danger... The list goes on and on. There are many other principles, but you get the point. Stoicism is attractive because it offers a way out for those who want to escape from the hustle and bustle of everyday life. Just disconnect yourself from social media for a while and see what happens. Maybe go visit some old friends or put your feet up for a few days. Do something with no expectations other than having fun and seeing how it goes. Finally, stoicism is attractive because it contains within its four walls everything needed to have a happy life.
