I used to consider these to be pretty worthless things too. After a while I started to realise that a lot of these things provide a lot of the same random platitudes that therapists typically provide too.
Given that therapists are a bit of a dice roll as far as the quality of advice you get, why not just instead make the advice given itself a dice roll. At that point, there’s a non negligible probability that the advice given by a half decent palm / star / tarot reader might actually be relevant.
Sure, it’s all just chance and luck, but when the advice ends up being relevant (or becomes self fulfilling in its relevance) and actually helps the receiver, why not?
(These learnings are brought to you by my ex who very patiently explained to me one of the ways I was an asshole when we were together. I’m now a bit more open minded and keep my eye rolls to myself behind my sunglasses)
