It depends on my mood what I go for, but overall I think The Fool is the best description. I cannot think of a better card. The Fool is unpredictable, prepared to see the answer, prepared to tackle the answer, has an open mind, and is not afraid of the dark. It won over Justice, which I think fits a lot, but sometimes I'm not doing a Justice-like spread with a Justice-like question.
Justice - I am very hardcore honest when reading for myself. For others, I will tell them the truth but not as harshly as I do when I am alone. I try to keep in mind that the truth doesn't have to be dark and awful as well. Overall, however, my tendency to throw in my own techniques on the spot, to experiment, and use information without any idea where it came from seemed more similar to The Fool.
