I believe so too.
Besides, doesn't every cell change with another cell within seven years? (I am not completely sure about that but I think I heard/read that somewhere) And if so, wouldn't also our "hardware" go through a change?
Now that I think about it; I've found out that I was more or less just pushed into a corner when I wasn't expressing the me I know from inside. And that made me try many different roles/personalities.
Would you understand my reasoning if I say that a circle that gathers circles, soon after becomes a square and when trying to break free becomes a triangle that longs to become a circle again?
