An international query came as follows,

Very disturbed by my son's sign, are all Geminis bad?
We read the characteristics of my sons sign. Nothing good to say about them. Cunning, selfish, manipulative, no follow through...even the good stuff was bad really. How do you feel about signs?
Answer
Astrology is not so simple as reading the general characterstics by the sign.

A lot depends upon the name you choose.......

A lot depends upon his ascedent at the time of birth.......

And last but not the least,
major influences are his upbringing, external influences like social circle, friends, peers, teachers, etc.

Birth signs and astrological charts do tell up how to prevent and guard against pitfalls in life so as not to succumb to the bad things in life. It can be used a helping tool and not as a master which dictates.
