I would definitely recommend journaling, as described in a previous post. I would also suggest pulling a "card of the day" for yourself. Think of what the card means to you. Be mindful of this card throughout the day, and jot down anything that happens which you find significant. Record these findings in your journal. This exercise can help you synthesize down to earth applications for what the card means to you.
Example: I draw the seven of cups card. In general, it is about having many options, some good, some bad. As a cups card it is grounded in emotion. I have drawn this card several times whenever I am having a day at work where I am scattered and daydreaming rather than doing what I need to. So for me, when I see this card for myself, I know it is usually telling me that I need to get my head out of the clouds and get my act together if I want to get anything accomplished.
There are many books/websites with card meanings, most based on the Rider-Waite deck. One good site that is pretty comprehensive (and free!) is:
Hope that helps. Best of luck!
