Inside anyone who has strong Aquarian influences is a person who is extremely uncertain of his or her true identity. The Aquarius ego is said to be the most precarious in the zodiac, probably because Aquarius is the sign of nonconformity. Intellectual genius, practical eccentricity, and mental oddity are all linked with Aquarius.
The typical Aquarius personality has a magnetic and powerful intellect. Putting this to good, practical use is the best way for Aquarius to build an identifiable ego.
