What no one tells twentysomethings like Emma is that finally, and suddenly, they can pick their own families - they can create their own families - and these are the families that life will be about. These are the families that will define the decades ahead.

Distinctiveness is a fundamental part of identity. We develop a clearer sense of ourselves by firming up the boundaries between ourselves and others. I am who I am because of how I am different from those around me. There is a point to my life because it cannot be carried out in exactly the same way by any other person. Differentness is part of what makes us who we are. It gives our lives meaning.
