Well, a good book is a must. I often suggest to those starting out to get the book “Power Tarot” and the reason I suggest it is because there are several areas–love, work, finances, etc.–that the book has definitions on. However, after time you will learn that you have completely different or expanded meanings for the cards. You’ll most likely find that at least one card has a different meaning for you.
Also, you must be patient and keep practicing. Tarot is not something you’re going to master in a matter of days. It takes years of practice to become good at Tarot.
