When we read about different zodiac signs, the common mistake that the majority of people often make is that they on their own assume that people's behaviour and conduct need to conform exactly with what is written in the Zodiac sign.
However, it should be understood that people's behaviour and conduct is not just governed by our own personality, but also by external factors that influence it, such as the prevailing circumstances, behaviour of the person/s with whom you are interacting, surroundings etc. Also, personality and behaviour are not the same thing.
Behaviour constitutes how we come across to others, mainly through our actions, our decisions and mainly the manner in which we communicate with others. However, personality defines our basic mental construct which, in my opinion. essentially remains the same throughout our existence, hence I believe is more genetic.
The characteristics that are mentioned for a zodiac sign essentially signify people's personalities and are much less about people's behaviour. Hence, if we are curious to know about a person's behaviour and are reading about a particular person's Zodiac sign then, in my view, it should be left to the reader's interpretation of what he understands from an article.
