Are there questions you won’t answer with the cards?
Standard limits [this is what I don’t do]:
Nothing about money, health/body or legal questions/concerns: seek out the appropriate professional.
No yes/no or timing questions: There are ways of “reading” the cards for these, but they amount to a more-elaborate version of flipping a coin; a mere mechanism to have something chosen for you.
No assurance about what someone else thinks or will do (in relation to you or their own lives). I can tell a story with the cards — it was my first-ever application of them — but I don’t recommend acting on it without actual communication with that person.
No ought-to advice: Never surrender control of your life for ease in the moment. Do the hard (good) work of making decisions and learning from the results.
