Well, I really don't buy into astrology for any practical purpose other than to make money off those who do. But it's great to have an historical perspective of astronomy that stretches back over five millennia to its origins. I can see how Babylonian astronomical observations got tied up with their religious beliefs to produce the mythology that became astrology. Then I can see how the Renaissance re-kindled the "spirit" of science, which shattered the geocentric myth and eventually gave way to Kepler's laws of planetary motion, Newton's laws of celestial mechanics, and the eventual discoveries of Uranus, Neptune and Pluto (discovered in 1781, 1846, and 1930 respectively).
Did you know that the ancient Babylonians had no knowledge of those last three worlds? They knew only the Sun, Mercury, Venus, Earth, the Moon, Mars, Jupiter, Saturn, and the "fixed" stars.
As for salesmanship, one of my first astrology teachers told me that "Everyone is a seeker, and there is a seeker born every minute". Then she told me that all I had to do was show more than tell -- that it was how I acted and how I presented the material that impressed the seekers and kept them coming back. Being an aspie (I didn't know it then), I would first deny any special ability, and then offer to show them how to produce their own natal data from their own time and place of birth. I guess my aspie shyness helped somehow; who knows?
Anyway, it was a lot of fun, as I knew that I was putting something over on people who would not have otherwise given me the time of day, and that doing so was (and still is) completely legal. I could see how easy it was for some "psychics" to con their clients out of their life's savings, but I never went that far.
