Before I knew anything about astrology, I saw myself as a friendly peacemaker who was easy-going and understanding. I saw myself as something of a Libra, and still see it sometimes, though I don't have any Libra influence, and I don't see any particularly strong aspects to my Venus.
Since I've learned about my chart I've come to realize that this self-image isn't true at all. I have an unfriendly disposition, sarcastic attitude toward life, a demanding emotional side, and a killer critic inside of me, lol. I'm also more of a fencer than a peacemaker, usually argumentative and judgmental, though I know I probably shouldn't be.
So, I've come to realize that the characteristics I used to see myself as having actually don't exist in me, or at least they exist in a much smaller regard. There are some Libra characteristics I do have, though, like indecisiveness and a wandering imagination. I feel like I have Libra in me somewhere, but I can't find the Venus influence that makes me this way (if it is Venus).
And, like you, Virgorising, I've also felt a Piscean influence, but it may be because of Neptune conjoining my Sun, because I also have no planets in Pisces.
