Hi silverwinter,
I think it's perfectly fine to set boundaries about the types of readings you're prepared to do based on how you see tarot and it's uses; I do that myself and I'm always wary of questions that are purely predictive because for me, we're all in control of our own destinies and think that to a point, we make our own futures with our thoughts and actions in the past and present.
I think it is possible to steer people towards questions that blend well with your view of tarot and how you use it though and I think that's what you may have meant when you said you're having trouble with the things people are asking you to read about.
For me, I'll read on any topic directly to do with the person asking for the reading so I won't answer questions like 'How is my ex's relationship with his current girlfriend?'..
If someone comes to me asking a purely predictive question like 'Will I get a new job in the next 6 months', I talk to them about how I see tarot, the future etc and try to steer them towards a question that I think will give them a more useful answer so something like 'What do I need to do to ensure that I'll get a new job in the next 6 months?'
I also think that tarot is descriptive and not the best tool for answering questions that need a yes or a no answer so I'll work with the querant to formulate a new question so something like 'Tell me about xxxx' or 'What does x need to know about xxxx?'
I've been working like this for years and I've never had a complaint from someone about how I change questions.. I think the important thing is to communicate with the people who come to you; explain why you find their questions difficult and work with them to get their questions to fit in with how you'd prefer to work..
Remember too though that tarot is sometimes just a bit of fun and not everyone wants an in-depth, psychological analysis reading
. Sometimes in cases like that I've found it's best to just lay down 3 cards and say what you see.
