I read cards as well. It's a lot of fun to be able to do at a gathering, and I like collecting decks because for like $20 I get an artist's variation on 78 different themes.

I also follow a guy on youtube, dude was a student at Harvard Medical School, now he's a psychologist and teaches there. He likes tarot and other divination systems too. He says that the process of trying to wrap your reality around what the cards say can force you into new perspectives, and that even the act of asking the question forces you to focus on something that you're uncertain about, which can help you identify issues in your life that are holding you back.
