Because outer planet Uranus rules your sign of Aquarius, you understand the big picture in life.
You have access to more information about the way things work than other signs, so you can become strong willed about your opinions, and even forceful in an argument. Others cross you at their peril!
The challenge for Aquarians is to not become too dogmatic, or entrenched in your beliefs.
Having an opinion about an issue is one thing. Shouting louder than someone to drown out their voice is another. Leave room for discussion and you may learn something new!
