Of course, you're just one case, but I hear about such things occasionally ... from people who usually believe in astrology, some of whom have struck me as highly intelligent.
Again, yours is just one case, and it could be accuracy by chance.
But when you hear, for example, that Indira Gandhi found astrology accurate enough to use in governing India ... and I don't think she was a fool ... I have to wonder if there is something in it.
Still, I'm basically very skeptical. I have tried to learn about astrology two or three times, but I just can't get my mind around it. I quickly forget anything I read about it or hear from supposed experts.
At times, I have thought about certain astrological 'truths' and found them vaguely confirmed in my own experience ... certain ideas about what Scorpion women are like, for example. (But that was then, and now I can't even remember what those ideas were.)
And I have had friends, one in particular, who seemed able to guess many peoples' signs.
Astrology makes no rational sense at all. My mind mostly rebels at the thought of taking it seriously. Most of what passes for astrology is surely crap. But I wind up unable to entirely dismiss it.
