Pisces are the dreamers of the zodiac. Caring and sympathetic they typically enjoy helping others and dislike confrontation. Highly empathetic and intuitive they can often read people on a level that appears almost psychic. Very empathetic they react strongly to the moods of others, often assuming those same moods themselves. Amongst the most creative of all the signs they often excel at everything from art to business, though motivation and inspiration is typically a key ingredient in this process and can be easily dampened by the realities of modern life. Due to this they're the sign which is most prone to depression, dependency and escapism.

One of the fascinating things about astrology is the patterns which exist. Pisces 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 Pisces personality.
No. The above traits exist if someone has a Pisces 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.
