Tarot for Self Discovery (Special Topics in Tarot) by Nina Lee Braden contains around 50 exercises you can do with Tarot cards in order to explore various aspects of yourself. Some of the exercises are light-hearted and fun, and some more in-depth and serious.
My choice was an exercise on procrastination; specifically, I have been hoarding information about something without doing anything with it. I'm good at gathering information, from anywhere and everywhere. This is what I do, it is both my profession and my hobby. I'm a little obsessive about it too, and I tend to hoard the results. (At this point, my psychologist is probably smiling broadly---hasn't she told me to stop reading and start doing? :-)
And that is the point: information does not become knowledge by itself; knowledge does not become expertise or wisdom without focus, attention and a great deal of action and experience.
So, my first task was to choose a card (face-up) to represent whatever I'm procrastinating on. Three-quarters of the deck ended up in my "possibles" pile (I also tend to be over-enthusiastic!). In the end I chose Trump V, The Hierophant (from the Rider-Waite-Smith deck) as representing wisdom, particularly in the spiritual domain.

Interesting: just the action of going through the cards and considering each in turn helped me focus on exactly how I would define the problem. Just this, in itself, was a valuable exercise.
Next, I had to consider my feelings about this card in general. Mixed. The Hierophant is about conventions, institutions, the external face of religion, the rules of society. While I can see the point of tradition and rules, I don't often get too excited about them, seeing them as binding, restrictive, boring, indicative of ignorance and fanaticism. Which made me think: do I resist working with information, exploring something in-depth, because I'm afraid of being restricted, losing out on something else that is exciting, getting bored with the practice of something as opposed to finding out new things? Am I so worried to be seen as ignorant, that I keep gathering without taking the time for reflection? Ouch.
The Hierophant also happens to be my "year card" (more about this later), representing lessons I need to learn this year. I have not been entirely enthusiastic about this thought. Teaching me to be more conventional, to obey the rules, to "fit in"? Surely I've been there, for most of my life. Now that I have managed to break free, to be myself, why on earth should I accept this ... this, representative of a patriarchal religion ... as my teacher? Studying the card, I started thinking about this man, often seen as a teacher or mentor---wise, focused and calm---as embodying something of my own goals and dreams. To have that calm self-confidence and self-awareness; the deepen my spirituality; to become wise and to help others find their own wisdom; to be confident in my knowing. I realise that I don't have to repeat lessons already learned, but that there is much to learn still from the this card. Focusing on something, restricting myself to what I have, may after all have more benefits than I had realised.
Next task: shuffle the deck and choose three cards---face down---to represent thoughts, emotions, and actions. I turn over the first card:

What on earth is the Fool doing in my thoughts? I said this out loud, and my husband started laughing. I do tend to walk around with dreams and visions, my head in the clouds, not noticing the abyss at my feet. The Fool carries his "bag of tricks" slung over his shoulder. Some say he has just completed his education (from some guru in the mountains behind him), and is setting out with everything he has been taught, but with no experience at all. How appropriate! The Fool also represents beginnings, and I think "my thoughts are telling me I'm just a beginner". Again, quite appropriate, and definitely "food for thought".
Emotions:

Nine of Cups. That looks like a happy guy, content, rich, even a bit smug. How does this picture fit in with my emotions around my project? I think: "So, while my thoughts are insisting that I'm just a beginner, my emotions suggest that I feel pretty good about what I know, that there is an abundance, and that I can 'afford' to be proud of what I have achieved." Hmm. I also see a suggestion, however, of the effects of over-indulgence. The man is rather plump, and that complacent smile will disappear very quickly if all those cups were to fall on him. So, now I'm thinking of being overwhelmed, which immediately feels right: I have been feeling overwhelmed by everything I have been gathering. Maybe it's time to sit back and just enjoyed the fruits of my labour.
Actions:

Trump XIX, The Sun. I think about light, and enlightenment. Taking action---as opposed to procrastination---can lead to wisdom. Good thought! What else? The sun suggests warmth, life, joy, energy. How is that for encouragement? Get on your horse and ride!
For the skeptics: I am not suggesting that some "higher power" placed these cards in these specific positions in order to tell me something. Maybe that does happen, who knows? But the process of finding a correlation between the images on a card and its position in a spread does shake loose, from a myriad of possibilities, one or more that "fit" the question or issue. Moreover, the associations you make will often reveal issues that have been rattling around just below the level of awareness, or emphasize whatever has been uppermost in your mind. As an example, let's look at the last card I drew, for a suggestion of what would be the best way to resolve the issue:

Four of Pentacles. Now this made me laugh. The card shows a man clutching a pentacle, with two more beneath his feet, and one on his head. I have been writing about feeling restricted, so instead of immediately seeing the card's traditional associations (greed, possessiveness, the need for security), I see someone who has restricted himself---who cannot move, for then he will have to let go of the pentacle in his arms, the one on his head will fall off, and the pentacles under his feet will skid away. And of course, he is holding onto his possessions out of fear, greed, or possessiveness, which all indicate that he is a prisoner of himself. All he needs to do is to let go!
I also look at the difference between the people on the other cards, and this one. This man is hunched over, fearful, clutching at his possessions. In contrast, the Fool is striding fearlessly (if foolishly); the Hierophant sits up straight, looking confident and commanding; while the child on the horse has flung out his arms in exuberance. Action vs constraint. Wisdom vs greed. Joy vs fear.
From this last card, I make a short list of things that I can safely "let go" of for now; I note one thing that I can do, immediately; and I resolve to put the the five cards on my desktop where I can see them every day, as a reminder.
In 45 minutes, I have generated more insights, ideas and actions to take about my own procrastination than I had managed to do in ... well ... a long time!
