Having had a personal reading done for me by some bird I used to know, I can say that I am an aquarian but my moon is rising in Leo, which to anyone who knows me, would not be surprising at all.
Here are the traits lifted from some website I googled.
Friendly and humanitarian (Nope and check(ish))
Honest and loyal (Check and check)
Original and inventive (Nope and hmm, nope)
Independent and intellectual (Check and check)
On the dark side....
Intractable and contrary (Check and check)
Perverse and unpredictable (Check and nope)
Unemotional and detached (Check and check)
I never read my horoscope as it is a pile of kack. Do I believe that my traits have come about as a result of when I was born? Hmm, not sure, but I do find it a bit strange that so many people seem to fit the traits of their sign - not sure how much of that might be auto-suggestion though.
I do, however, do tarot cards, which generally tend to be accurate a lot more than not.
