Look up Carl Sagan on Astrology. You could probably find a video on youtube.
He points out how, because of the gradual shift of our planet’s axis and orbit, the sun no longer even rises within the same constellations as it did when astrology was in its infancy, actually making people a different sign than astrology labels them. I can’t remember if you have to go back a month or forwards. Regardless… pick up two different newspapers on the same day and compare their horoscopes. I think you’ll soon realize that they usually fail to match and that somebody somewhere is probably making all that crap up.
