I've watched people get really invested in all sorts of divination over the years, and tarot is almost always confirmation bias - you remember the hits and forget the misses, especially when a reading is vague enough to fit multiple situations. The cards themselves have no predictive mechanism; what actually helps is that sitting down to reflect forces you to think through your options, which is something you could do just as well with a journal or talking to a friend. Your friend probably isn't wrong that it's helped her make decisions, but that's because the *process* of deliberation works, not because the cards have special knowledge. If you enjoy tarot as a reflective tool or creative exercise, that's fine, but treating it as an actual prediction method is where you start fooling yourself.
