I also don't believe in psychics, but I do think that someone skilled in this kind of intuitive stuff can really help you think about your situation from the outside. I mean, that's what psychotherapists do, and many are very good at it. I think it would be fair to be critical of the style of astrologers as compared to a good therapist, but like you, I think that sometimes the kind of serendipitous input from such a source can be very interesting.
