Peace Sistah:
First and foremost, I am glad to see that you took the time to take a look at this. It is always great to learn something new everyday.
Secondly, Astrology as applied to you can work like this:
Think of a photo with the Pisces symbol of the Fishes in the background. Now add on to that an image of a scale (Libra), image of a bull (Taurus), image of a water-carrier (Aquarius), and an image of a crab (Cancer) - the overall picture is not so 'Piscean' now, is it?...
More often than not, most people are far more than their Sun signs. I say this assuming that you are a Sun-Pisces. Yes, you may be a Pisces, but that does not mean you will embody all of the Piscean characteristics. For example, I am a Sagittarius, and I embody many, but not all of the Sagittarian characteristcs. You also have to consider the exact placements within your signs. For example, someone born at the end of February would not "act" the same way as someone born in the middle of March. There is a reason for that, and further delving into Astrology would explain that.
Consider that along with your knowledge of Pisces, as well as other signs. Astrology is one of those sciences where the deeper you get into it, the clearer things are.
