The first thing you need to be aware of is that many people who use astrology tend to abbreviate the names. I mean, Sagittarius has five syllables and it's so much more convenient to abbreviate it to Sag. I've yet to meet a woman who would relish that.
Sagging is not what you should aspire to. Have yourself reallocated to a more robust sign, or switch to Chinese astrology.
Personally, I think astrology works. I'm Aries -- a Ram -- and I fathered five kids, so there MUST be something in it. Switch me to Chinese astrology and I was born in the Year of the Water Buffalo which is about as close as you can get to a bull.
