Most forms of zodiacs are generic enough to suit different people, giving the perception of accuracy. Like many here, I don't believe in any of these, including chinese zodiacs, signs, feng shui, etc.

Just to side track a bit..... As far as I know, successful politicians and tycoons have sworn by feng shui, but if you really want to believe in it, you've gotta lose a lot of freedom and it kills creativity.

Anyway, a quote from The Matrix:

Morpheus: Do you believe in fate, Neo?
Neo: No.
Morpheus: Why not?
Neo: Because I don't like the idea that I'm not in control of my life.

I feel the same way.
