How to ask a question the deck can answer
A yes-or-no reading is only as good as the question you put to it. The cards do not mind being asked anything, but a vague question gives you a vague verdict, and you will read your own hopes into the result. A little care up front is what turns three cards into something you can use.
Start by making the question genuinely binary. "Should I take the job?" has a clean yes and a clean no. "What will happen with the job?" does not — there is nothing for the cards to vote on, and you will end up squinting at three images trying to invent a storyline. If your question can't be answered with the word yes or the word no, it belongs in a three-card spread instead, where the cards are allowed to describe rather than decide.
Keep it about your own move, not someone else's mind. "Should I tell her how I feel?" sits in your hands. "Does she like me?" asks the deck to report on a person who isn't here, and the answer, whatever it is, won't tell you what to do next. The most useful yes-or-no questions almost always end in a verb you control.
And pin it to a frame. "Should I look for a new flat?" drifts; "Should I start looking for a new flat this month?" lands. A timeframe gives the verdict edges, so that when it comes back leaning yes you know what you are being nudged toward and roughly when. Ask once, take the answer — including the reservation a reversed card is pointing at — and resist the urge to re-draw until the deck finally agrees with you. The first honest answer is the one worth keeping.
