What am I?

What am I?  Yes, I'm layer upon layer of happenings; some of my doing and others not.  Yes, I have choices but there's something inside me that is always quite strongly and magnetically attracted to my eventual 'choice'.  What am I?   I'm not what I would want to be; I'm what my environment has formed based on my inherited genetics.  I don't like what I am but the foundation of 'what I am" was taken completely out of my hands.
