Do you put much thought into a persons sign?

It just gives me an idea and actually it's not good stereotyping,cause you become a close-minded person.But I do think that signs can give you a deeper insight of a person characters,cause they point out certain characteristics of the people born under a certain zodiac and make you realize some of them.But I find observation to be more right.I do believe in the zodiac but that's as far as you go,if you can't judge a person's character by yourself then that's really disappointing.So what the zodiac offers is some kind of psychology.You just don't have to become a fanatic.
