Often we can change things, and a realistic attitude - including envisioning worse case scenarios - actually helps to accomplish that change. But if you truly cannot do anything about something, then why on earth would you want to make things even worse for you by falling into despair? It seems like adding a self-inflicting injury to the already existing one.

We still live in a world of such gross injustice and inequality, that only privileged people like ourselves can afford to think of eros and art as top concerns in life. They are important, for sure, but I think it's high time to shift priorities around, away from selfish indulgence, and toward more concern for the wellbeing of so many others who suffer atrocities, injustice, and famine, all over the planet.

In my mind, there is no reason why Stoicism shouldn't become as popular as Buddhism, especially in the Western world, where the dominant culture, Christianity, itself absorbed a large number of elements from Greco-Roman Stoicism.

I don't see any Stoic practice as problematic or risky, but I would advise to engage in extreme versions of the negative visualization exercise only if you are an advanced practitioner. The negative visualization is a meditation during which you visualize, slowly and deliberately, something bad or discomforting happening to you.

The Stoics thought that a fundamental insight into human life is that some things are up to us and others are not, the famous dichotomy of control. Up to us are our judgments, decisions, and actions; everything else is not up to us, because it is influenced by external factors.

If a theory purports to explain everything, then it is likely not explaining much at all.
