Yes, I like the way you put it. It's crazy to think that we're all so pliable though. Our parents, our peers, and history all teach us that we have an identity, a certain "best" that we are striving for, but when I look at myself I see that even within the past year I am a totally different person. The way I think, the way I act, the way I react... it's all different from another version of myself from the past. Yet I'm still the same person!
In my mind, nobody ever really "grows up". We just learn how to act in public, and life suck the joy out of us. Going into Freudian territory, we only learn to reign in the id, and we do this through socialization. Learning to make choices is another fundamental part of the process.
Now MF will be able to go deeper into this Inception style, but that's my basic philosophy.
