Does my Zodiac sign traits describe my personality?

For many years I believed what I read under the sign, Libra, was an accurate description of myself. This belief in astrology came from my mom who told me about the signs at a young age. A Libra is supposed to be balanced, and be very social, and is also indecisive and can have mood swings. I thought that those traits described me very well.

Now that I am older, I believe that since you read horoscopes from a young age on, you shape yourself to fit the traits you read. I saw a documentary where as a test, a professor gave students a "horoscope" and told them that was their sign. What the professor didnt tell them was that he gave everyone the same horoscope. Turns out, the majority of students felt the horoscope was an accurate description of who they were!

So, I no longer subscribe to the notion that the stars you were born under influences who you are as a person.
