Take the cards lightly. Something about divination is that it is better as a guide than a concrete answer. Divining about important questions for one's self can end up with not-so-optimal results, depending on a lot of factors. With yes-no only questions, the way a question is asked may be a limiting factor, and sometimes a 'no' might be a 'possibly,' for example. That's partly why some people prefer not to use a divination method with a strict yes-no answer system.
Therefore take the answers lightly.
