Toss the LWB
The LWBs is often a quick and dirty crib-sheet that has the mindset of being for a party gift rather than a serious tarot reader. To be fair, this doesn't apply to all the LWBs. Sometimes with newer and different decks the writers of the LWB have been more self-aware. But with the old stand-by, Rider-Waite, they're still pretty quick and dirty and not real scholarly. The usual recommendation is: Toss the LWB. If you get a special deck, get the special book that comes with that deck. Or, alternately, there are study groups here that do an amazing job of examining different decks in details.
As for Rider-Waite, read several different books to get the gist of the cards--and to find that book which works and speaks to you. HOWEVER, the one thing that never works well is flipping the cards with one hand, and flipping through the book with the other. This is commonly a very slow and ineffective way of learning tarot cards. There are three common methods of absorbing the meanings so you don't need to keep flipping through the book. No one method works for everyone. Pick the one that works for you--and mix-match until you find it:
(1) Journal/Meditation/Instinct method: Do not use any sort of book at all. Go though the cards, one a day, write down thoughts, what your instincts tell you, get to know the card (study it's details) as if you created the image. And by all means use this site (this very part of it) to discuss your thoughts and read what others think. Some beginners even put the cards under their pillows to dream about them. In this method, you treat the cards as if they were individuals you're getting to know intimately and personally. You essentially spend the day with them.
(2) Keyword method: Memorize the Majors--what they are in order. Just memorize them (Fool, magician, High Priestess...). Now give each one a keyword. One word that fits what they mean--a consensus meaning from the books (Fool = Beginnings). If you look on the internet you'll find a lot of suggested tarot keywords. Memorize card and keyword. For the minors, connect the keyword of the 1-10 majors (Magician - Wheel) with the minors and suits to form a kind of sentence. (Cups = emotions, so if Empress = keyword: "Create" then 3/Cups = "Create Emotions"). This gives you a flashcard method for what the cards mean. Warning: this method is good for getting to know the cards but limited as you develop.
(3) Books + Story: Go through the deck card by card, reading the meanings from one or more books (or using this website). Then, using those meanings and the image on the card, make up a story for it. After you've made up a story for each card, try making up stories about the cards together. Like a story for each major, and a story for the majors from Fool through to World. Also stories from Ace-10 of the minors.
Keep in mind that learning tarot cards takes time, like learning a new language or skill. Don't be impatient. The journey of getting to know the cards, like getting to know individuals, is part of the fun, part of the discovery. By all means, take detours if you feel like it, and use this site to ask questions and explore answers. Enjoy yourself and if one method doesn't do the job, try another. Also, don't worry if you feel overwhelmed. We all do in the beginning. We can promise you there will be breakthroughs, revelations, and it will all come together. Welcome to AT!
