Perhaps you should cruise the DECKS section of this site and see if one of them "speaks" to you in some way. By that I mean attracts you, gives you a sense of possibility, pleases your eye or mind, fascinates you, or just seems interesting in a way that could lead to engaging your imagination. Any of the Above or all of the above.
Get the deck.
Go to a bookstore or on line and cruise tarot books, same process, with an emphasis on making sense to you. Some books are workbooks...look at these, too...they may be best for you. 21 was to read a tarot card is a favorite of mine, but you might (or not) connect with it. Get one book only.
Spend time with the deck, just fooling around. spend time with the book, concentrating, taking your time. Move slowly. Be gentle with yourself. Write your readings down. Use small spreads--3 to 5 cards. Go back and rate your old readings for accuracy. Learn from the process.
Take the pressure off yourself and let yourself grow into Tarot.
