This is perhaps the second-most used spread in my practice aside from my daily draw.
And it should be pretty obvious why I like this one so much. Three cards. Quick. Easy to remember. And the best part...it's very clear.
The first card shows you yourself in this situation.
The second card shows you the reality of the situation.
The third card gives you advice for the situation.
I have yet to think of a question that this spread doesn't work for, but let me know if you do.
