I did some Tarot card readings back in college. It was weird. At the time, I had little idea what I was doing. I got a deck from a friend and a book from the library. I set up some candles in my dorm room and "conditioned" each person who wanted a reading by explaining the process and emphasized that they had to concentrate etc... I had a book from the library that explained the cards. Each card had so many different definitions, I just picked one that fit the person and the placement of the card. People considered my readings "accurate." Now, I know why. People want to believe. They don't count all the "misses" you have and only focus on the "hits" (the answers you get correct). I really wish I'd have kept track of the misses and hits, but I didn't. I know now that all I was doing was cold reading.
Without knowing it, I was using a technique used by all magicians and mentalist called "Cold Reading." Do a Google search and you'll find links like this: Australian Skeptics and JREF. I'm sure it wouldn't take me too long to get good at this. My problem is that I'm a bad liar and all my friends know me as an irritating skeptic. I also like to think I have ethics and morals that preclude me from taking people's money by preying on their emotions.
Please do some critical thinking before you spend money on psychics, mediums and card/palm/leaf readers. Use your money to pay the rent, feed the poor or save the whales. if you like.
Better yet, get these books and learn how to critically think: The Demon Haunted World or Flim-Flam
