The word personality finds its origin in greek(persona) meaning mask.So by its very nature we wear different masks at different times and therefore portray different images to different people.Also if you study the works of Alfred Adler and particularly the"family contellation" as he calls it, you will realise that it also depends on what position we are in the family.For example, the first child will always try to be a parent figure to the other siblings and therefore tend to be righteous and stay on the side of the law and often end up in such careers. The second child will always find competing against the first a struggle and therefore will tend to make their mark in life in the opposite direction. The youngest in the family learn how to get everybody wrapped around his/her little finger and tend to make a good career in acting.
