Oh I'm superstitious about a great many things but I try to make it as useful as possible by being the most superstitious about not practicing regular gratitude. So for instance I'll "wish" or "bless" someone with something like "a boring shift" because that's the kind of thing it's important to remember to be grateful for. Or instead of saying it's "quiet" (a common bad-luck superstition in healthcare), I'll comment that "I have been blessed with a good night so far."

A core component of my spirituality that I've reflected on lately is that regardless of what I do or don't believe cosmologically, spirituality and religion offer a huge amount of emotional / psychological tools that have stood the test of time and appeared across multiple religions in various forms due to sheer usefulness. These include things like community and regular gratitude and mindfulness practices.

They absolutely can and have been analyzed and implemented in other ways, but that requires a lot of research and very careful coordination of a lot of individual components. Meanwhile I've found a remarkable amount of success emotionally and psychologically in connecting with a faith community that has all those things built in and which has a LOT of other people who are doing the same thing to support me sticking with it.
