I read Tarot cards. Don't ask me how it works, I have no idea, although I suspect my goddess may have a lot to do with it! The readings never fail to amaze me and I've not had any complaints from those I have read them for, even though the readings are definitely not always positive. 

Please don't ask me to give you a reading on line! I do not accept money in any form for a reading, I think my goddess might get a tad peeved if I were to charge for her services - think about that if someone asks you to pay for a reading.

I see Tarot as a guide, not a set of rules, nothing is so set in concrete. However, they do tell a likely set of eventualities. No such thing in my book as self fulfilling prophecies.
