My own beliefs and personality determine this. I am the child of my parents, and will always be. But everyone becomes an adult at some point, and they must learn to live on their own. That is not only my own belief, but my father's as well. One does not determine when they are ready themselves, that is something that comes with time.

Recognizing that in itself qualifies you as one.
If that's the case then there have been very few adults to ever live on this planet.
