I too am a sceptic - in the sense that there are people (including situations involving myself - the things I read for myself are peripheral issues, or issues like my love-life which is essentially separate from what I think is my "purpose") I daren't read for just in case I can't handle the answer, and in the sense that I feel too emotionally involved with to make proper sense of the answers.
But I came late-ish to the tarot in the sense that I wanted something to "channel" divinations/clairvoyancy, so I guess I ought to bite the bullet and see what the cards say for some of the above. As I get more confident that I am generally along the right lines for these people, it seems much more of a temptation to want to read for them despite feeling that I might not be able to handle the outcome.
