I could not begin to tell you :) Far smarter men than me are still debating how much is genes, how much is early childhood influence, how much is the result of what you experience along the way, etc. I don't suspect we'll have anything remotely close to a conclusive answer anytime soon. My guess is it's something like baking a cake; the batter (biology), how mixed or lumpy it is (childhood), and how it's cooked (life experiences) will all play a role, but aside from the extremes like the eggs missing or being grossly under- or overcooked there's no good way to accurately gauge how everything comes together to produce what it does.
