hmmmm, never thought about it like that. i would think that i have a "core" personality that consists of what i learned as a small child. then, there would be layers that have come from my life experiences, which have been varied and affected me greatly. wow, i guess that i believe that there is my core, overlapped by the pieces that i've added throughout the years. does that make sense? most of thhe time i know who i am....but when i have doubts, it really bothers me.
