Capricorns are a favorite of mine, they are typically hardworking and ambitious. One of their more annoying qualities is their tendency to be perfectionists but that may be because Scorpio can be stubborn to the point of wanting to figure things out themselves or do things their own way.

Of course, this is all generalized textbook stuff. Anyone interested in a deeper knowledge should refer to their natal chart
