My advice is to write it all down for future reference. Include the date, cards pulled, the question asked, and any feelings you have about the situation the cards state (how you think it relates to your question)
You would be surprised to know how many times I did a review of the reading, only to see what the cards actually meant...interpretation can be tricky sometimes....especially if you are close to the situation...
I use the mythic tarot deck.... I find it really easy and the book interpretation to help me understand the cards individually... then I apply it as a story of sorts... usually it tells me what I already know and then adds. I typically use a ten card spread.... the first six cards tell me past and present, and the last four are my 'addition'/prediction
I worked with a dragon deck for a long time and had a harder time than I should of had. Turns out that deck is just not suited to me, and my mother thought of me last Yule and gave me a brand new pocket Rider Waite deck. This deck definatly likes me, but I try not to lean on it's use too much. I have a tendency to overdo the Tarot readings a bit. I only really do a deep reading every 3 to 6 months now. Only a smaller reading if I really need some insight on a problem or situation at the time.
I also do readings for people that ask it of me. I don't charge though. The people I tend to read for are down on their luck as it is. I only offer a guiding light to help keep them on their path. But I have never had a problem from anyone if I just didn't get an answer they liked. I hope that's because I explained things proporly.
It had to be the Waite deck for me. My dragon deck never really spoke to me. As soon as I touched my Waite deck, it was talking.
I needed a better grounding in the basics before I go back to the whimsical stuff. Need the concrete stuff right now.
I really enjoy reading Tarot. My favorite deck is the Gilded Tarot. The artwork is so beautiful and really resonates with me.
