Virgo is the perfectionist of the zodiac, typically professional (outwardly calm, reserved and precise) while seeking to improve any process that they are involved in. If a Virgo sets out to do something they typically don't rest until it's done very (very!) well.
Virgos like details, facts, lists, organization (bringing order from chaos). They are objective, intelligent, refined and quick witted. In relationships their serious and subtle demeanor often makes them tantalizingly sexy and provocative. Virgos enjoy mental stimulation and while outwardly calm they are typically always inwardly active and often have trouble relaxing. The Virgo need for perfection often extends to a need for efficiency. This can manifest in all life areas such as being frugal (efficient with money) and preferring 'productive' (efficient with time) leisure activities.

One of the fascinating things about astrology is the patterns which exist. Virgo personality traits certainly aren't random. They come from a combination of the signs ruling planet, element, polarity, house and quality. All of these are also used (consistently) elsewhere within astrology and come together to form the unique package which is the Virgo personality.
No. The above traits exist if someone has a Virgo sun sign. However every individual also has other planet placements (Moon, Mars, Venus etc) which modify this behavior. In some cases one or more of the basic personality traits listed above will be modified or even replaced. Only by examining all the planet placements for an individual can we get a complete picture of their unique personality. A skilled astrologer can often calculate these backwards from the ways that the basic sun sign behavior is being modified.
As children we are subjected to many experiences and influences. These can lead to a determined effort to modify our personality and behavior. The traits still exist, but they can be over ridden by free thought. It's fairly common for negative traits to gradually diminish as a person gets older, wiser and more socially adept.
