If you need a quick and dirty introduction to the Tarot.. find a deck you like - art that speaks to you, pictures that tell YOU a story - and THOROUGHLY READ the little booklet that comes with the cards!
Tarot is a skill that grows on you, but "I can’t understand, I can’t do this" is no longer an excuse. Tarot isn’t about memorization -- it is about interpreting what the cards say to you. The instructions that come with a deck provide enough basis to understand what the cards initially try to say. Your psychic intuition will take over from there.
