Why do you have starsigns?

Star signs are kind of like psychic things. they are supposed to tell you about yourself. My star sign is taurus. It says i am like a bull aggressive but hard working and kind. and in my case its true, other star signs might not fit the subcription of other people. i have to say im superstitous and believe in all this stuff bottom line star signs are suposed to tell a little about yourself. :):):)
