Everybody is unique, so even if they follow generalized traits, there are going to be mass differences in day to day activities, hence the generalized nature of daily horoscopes. No one can predict from afar what your nature will do every time it is faced with the daily rigors of life, but if you ever have a live reading it is uncanny how closely a stranger can nail your personality if they are a decent astrologer. From afar there is not enough information to accurately predict what you might do. A personal reading's effectiveness has largely to do with the information available to an astrologer in a one on one situation. They can ask questions that tell them what your Sun sign and your Moon sign are, explaining why you are generally relaxed but chatty when nervous, or why you appear awkward in general but are cool under pressure. Essentially, the rising sign in astrology is the key to the individuality of your astrological personality. It is your astrological chromosome.
Thankfully you won't have to spend decades learning ancient math and new techniques pouring over ancient scrolls and little pocket astrology books to figure out the riddle that is your rising sign. Thanks to the internet and the huge interest in the rising sign, there are tons of sites dedicated to helping you find your very own exact birth sign.
From Astrology: rising signs to Jeff Prince to astrology.com, there are literally hundreds of sites that can help you decipher your rising sign. These sites can help you to get the one on one type of assistance and individuality that you can receive from a live personal reading. Perhaps nothing makes the hair stand up on the back of the neck like a personal reading that nails your personality profile, but these days, if you search hard enough on the internet, you can come pretty close.
Thanks to modern technology, with a bit of time and effort, you can find your own birth sign, and begin to utilize rising sign astrology to its fullest potential, and maybe find some answers to questions you've been asking since the time of your actual birth.
