Each sun sign has its own challenges and weaknesses. Many people talk about their positive traits. People will proudly say what sign they are and exactly what is good about it. But the more you know about the sun signs, the better you can understand people. You'll know exactly who gets whiney and who is a true hot-head.

But knowing about the challenges and weaknesses for each sun sign can help you relate better to people.

But beware - like everything else, there's a dark and light sign of the Zodiac force. Here is the unvarnished truth about the zodiac signs - the good, the bad and the downright ugly.
