Parental Guidance?

Because of a teen drama "The O.C.", get to 'know' this young actress Olivia Wilde. Looking at her bio (picked a few below), I was wondering what would have bred a person with such diversified profile and exposure (if not character). Is it more 'cos of the bring-up? or 'cos of the individual's will? or 'cos of the value and system fostered by a culture/society? or all-of-the-above?
