The zodiac describes the element that corresponds to you and your nature. However, you don't necessarily have to like it. Everyone should work with all the elements. The elements are water, earth, fire, air, and spirit. If you feel that you aren't satisfied with the element of your zodiac, you can mediate on it and concentrate on the nature of each element and everything associated with them. Once you feel a certain wholeness and a sense of belinging with a certain element, then you will know it is your element.
The zodiac is actually the wheel of signs. Your personal astrology is the position of he astrological planets at your time of birth. You do not have a single sign, as you have planets and calculated points in several signs. While your natal astrology can influence what elements you are most gifted with, you do not have "an element." Different elements are useful for different things, so concentrating primarily on the element you are most gifted with would be like trying to build a martial art around a single move you are most skilled with. The idea that you have "an element" comes largely from mystical-inspired fiction like that stupid Last Air Bender anime. And finally, ice is not generally accepted as an element. The elements are metaphors for particular natures and aspects of human existence, not physical forces to work with.
To find your element find something to symbolize the elements for earth: rock, water: water, fire: candle, air: feather, for spirit us your self, and just medatate for a while on each element seperately moving you'r hand over each one, the one that calls to you the most is most Likely your element .
