Can you guess what zodiac sign I am?

We are not a sign.

We have ALL 12 zodiac signs in our astrological birth chart.

What we are, are our 10 "planets", including the Sun.

What you call your "zodiac sign" is your "Sun sign", the sign that Sun was moving through when you were, born, and it is only a small part of the whole picture.

And what astrology identifies is what goes on INSIDE you .. your inner personality dynamics. It doesn't do a good job of identifying outer behaviors.

Looking at each quality you have given us, only a small number of them pertain to anything that astrology would identify. To help you better understand astrology:

- I'm an identical twin = astrology doesn't pertain to this

- I play acoustic and electric guitar = astrology doesn't pertain to this

- I love 60's, 70's and 90's music = astrology doesn't pertain to this

- Some of my favorite bands are Pearl Jam, Nirvana, Pink Floyd = astrology doesn't pertain to this

- My favorite colors are red and blue = astrology doesn't pertain to this

- My favorite book and movie is Into the Wild = astrology doesn't pertain to this

- I'm interested in philosophy and psychology and art = Astrology DOES pertain to these ... philosophy is Jupiter, Neptune, 9th house. Psychology is Libra, Scorpio, Venus, Pluto, 7th house, 8th house, 9th house. At is Venus, Neptune, 5th house. Any combination of these.

- I'm a thinker, I always write down my thoughts and daydream in school = Astrology DOES pertain to this. You would look at the sign, house and aspects of your Mercury .. not your Sun sign.

- I'm a total slacker when it comes to school and always do assignments last minute = astrology doesn't pertain to this. You are merely undisciplined.

- I'm extremely stubborn when it comes to trying out new things = Astrology DOES pertain to this. Either a lot of planets in Fixed signs, or Fixed signs angular, of planets in Fixed signs that are conjunct the angles.

- I'm a girl of habit = Astrology DOES pertain to this. Any of the Earth or Fixed signs

- Its easy for me to make friends (Fire, Venus, Ascendant aspects), but I can be reserved (Saturn, Water signs, Ascendant aspects) and would pick a Friday night alone reading over a party (Saturn, Water signs, Pluto in 1st house, Neptune angular, Air signs).

There you go .. for each trait, ONE of those influences is going to be present in your chart.

Do up your chart.

You mainly told us traits of Pisces, Aries and Gemini, I would say you could be a Pisces sun with possibly Aries or Gemini as your rising or moon signs?

Aquarius

Sun, Moon or Rising??? You can come off as one of these signs or somewhere in your birth chart alone. Sun sign astrology is not everything to you. I need more info to give you my best guess.

Gemini?

Two face Gem?

Gemini definetly.

Sag?

sounds like libra
