The I Ching is a 3,000-year-old divination text, not a decision-making algorithm, and treating it like one is where people get disappointed. Where I'd push back on the "just reflection" take: it's *only* useful if you're already leaning toward an answer and need permission to commit to it - if you're genuinely undecided about your job, flipping coins (which is basically what the hexagrams amount to) won't break the tie any better than asking a friend would.
What actually works is sitting with the interpretation afterward and noticing which parts make you feel relieved or disappointed. If you read something about risk and stability and feel a knot in your stomach, that tells you something real about what you actually want, separate from what the text says. But that's just introspection wearing a fancy costume. For major life moves, you're better off listing pros and cons, talking to people who know your situation, or getting concrete about what "rough patch" means - is it the work itself, the manager, burnout, or just needing better pay?
