|You're going on a journey......|
and acquiring an expensive habit
Bought my first Tarot deck yonks ago - but couldn't read with it without referring to the Little White Book, which is no way to read Tarot cards!
I joined TABI (The Tarot Association of The British Isles) in, I think, 2003 and undertook their training course. I could read the cards competently after that.
However, it's an ongoing process - you are always learning and discovering something new to add to your knowledge about the cards.
