On the Outside
The Capricorn personality is very grounded in reality; it's the rock that everyone else loves to lean on. For the most part, Capricorns are:
Quietly strong-willed
Self-assured and truly know who they are
Comfortable in any social situation they choose to participate in
Although Caps sometimes have a reputation as being a bit stodgy, they often astound their companions with their sharp and sudden wit.
On the Inside
Caps are highly dependable, yet they can still suffer inwardly from mood swings that carry them from the heights of euphoria to bouts of depression. In most cases, they are adept at concealing these conflicting moods in public. It is only their closest friends and family who are given a glimpse of this inner turmoil.
