"Do one thing, and do it well," and "Speak the truth plainly, for the the plain truth is plainly true." I approach the Tarot with the perspective of modern psychology and human behavior research, not new age mumbo jumbo words that can mean "all things to all people." The only tool for divining the truth that I use is the Tarot. I have numerous tarot decks on hand (generally I stick to only two of them) in the event the question is more complex than just simply, for example, "how does s/he feel about me?" This gives me the ability to look into complex layers on a matter.
I do not need more than your question, and the first name(s) of anyone if the question is about them. The cards themselves are as much a part of the Universe as you and I, but unlike you and I do not resist the movements of the influences the Universe and your question impose upon them. They will answer specifically and without resistance.
I will ask you your question. We must focus on only one matter at a time (romance then career then a family matter, for example). After I shuffle and lay down the specific spread regarding your concern, I will be able to answer any question specific to that concern you have (without needing to use another shuffle even if you think it is a new question; so long as it is about the original focus, it needs no new shuffle or new cards). My method is considerably fast in this way
