Personality and mind are what make us who and what we are. They are there from the beginning they do not learn them but they do evolve due to external influences but that doesn't mean they are not the things that make you who you are. Changes in personality do make you a different person but not a different entity you simply change the ways you view existence.
quote:
Minds can be dangerous places to visit.
This is a very good point, one should be aware that the mind is powerful and all things powerful are potentially hazardous.
